Two objects moving toward each other Two cars entered an Interstate highway at the same time and traveled toward each other (see Figure 3). The time = 20 secs. The ratio of time taken by B and C to overtake A from the time after they start is 2:3. 75/x – 75/(3/2)x= 125/(10*60) — subtracting the times travelled by two them hence trains wastage time, when a person is moving with speed x km/hr is reaching office in t time. So the slower train is moving at the rate of 40 mph.
Assuming the distance covered in the 1st part of journey to be ‘d’, the distance covered in the second half becomes ‘630-d’. 60km divided by 10km/h=6 hours Infinity is a floorless room without walls or ceiling. Hot Appu and Gappu both start running around a circular racetrack in the same direction, each of them going at a constant speed. Therefore, its normal speed is 50 kmph. The variables x and y represent the usual speed and usual time to travel distance d. Speed comes out to be 20 km/hr and the time taken is 3 hrs. what is the distance. How far from the new market will they meet ? Let the speed be x. and time be y. A.T.Q, (x+4)(y-1/2)=d and (x-2)(y+1/3)=d. Let the speed of first car be x km/hr & let the speed of second car be y km/hr If travelling in same direction Distance travelled by 1st car = AC = AB + BC Distance … If the speed of the stream is 4 kmph, what is the boat’s speed in still water? Not Replied The train takes 3h to cover 150 km.
Example 3. s*t = (1/3)s*(t+30) → t = t/3 + 10 → t = 15. what is the time it flew at each speed? Distance: Speed: Time: First person: d: 3: t: Second person: 20-d: 4: t Assuming the distance travelled by the first person to be ‘d’, the distance travelled by the second person is ’20-d’. Let us take a look at some simple examples of distance, time and speed problems. A car takes 4 hours to cover a distance, if it travels at a speed of 40 mph. Let ‘s’ be the speed of Meenu, Time taken by Meenu => t1 = 48/s Distance travel by P in 2 hours is equal to distance travel by Q in t hours. In a bike race 2 riders are going the same direction towards the finish. I listed the speeds of the cars, and their direction of travel. Total time taken by Deepak = 30 + 37.5 = 67.5. There is nothing wrong with the statement. I think there is some mistake if speed of first car is 50 then only it satisfies given option. A boy travelled by train which moved at the speed of 30 mph. TCS Numerical Ability Question Solution - Two cars starts from A and B and travel towards each other at the speed of 50 kmph and 60 kmph respectively. Therefore, the problem happened after 200 - 150 = 50 km. less. Solved Example 1. Say the slower object starts it's movement at 50 meters and the faster one starts at 0 meters. Both start from point A at the same time and reach point B 75 KMS away from A at the same time.
If they travel towards each other, they meet in 1 hour. Answer: 9 hours. Since it’s harder to look for one variable since both are absent, you can use, 3d/ d( V2V3 + V1V3 + V1V2/ V1V2V3). Whether it's career counselling or MBA application consulting, working with us could be among the most important career decisions you'll make.
Gas costs 2.56 a gallon.
Let the length of the train to prod past a point be the intrinsic distance (D) of the train and its speed be S. Its speed, S in passing the electric pole of negligible length is = D/12. She stops every 20 km for one hour to have a break. Find the distance he travelled by bus. How many kilometers did Bill drive from home to work? A boat covers a certain distance in 2 hours, while it comes back in 3 hours. priya reaches manamadurai and at turns back meeting meenu 12km from manamaduai.
A boy travels by a train to visits his father in Durban. Two cars starts from a & b and travel towards each other at speeds 0f 59 kmph and 60 kmph respectively at the time of their meeting the second car has travelled 120km more than the first the distance between a & b in kms is a)720 b)1230 c)1320 d) 600 Asked In TCS dhritiman (4 years ago) Let the time after which they meet be ‘t’ hours. Thus, 48/s = 72/(s+4) => 24s = 192 => s = 8Km/hr. You may need to download version 2.0 now from the Chrome Web Store. (a, 4) and (3, b) are (5, -2), find the values of a and b. The time is ‘t’ for both of them because when they meet, they would have walked for the same time. a) sue drove 10 kms from home to work, and the ratio of distance driven from home to work time to drive from home to work was the same for Bill and Sue that day. If the cars travel in the same direction at different speeds, they meet in 5 hours. People do not make any mistake when they say life is a mathematics but they make blunder when they think mathematics is merely a calculation. Another train starts from madhupur for kolkata at same instance. If it catches up with the first train in 4 hours, what is the speed of the first train? From Sajal Newmarket, Rickshaw was 6 km per hour and Kajal left the same place for 4 km per hour . Now make body A stationary and take the speed of B in reference to A, so relative Speed of B = sum of their respective speeds = 20 + 30 = 50 kmph ( as they are travelling in opposite directions).
on solving we get x/y = 1 + sqrt{2} or 1 - sqrt{2}. Appu goes all the way around the track and catches up with Gappu. The distance between Delhi to Mumbai is took .Two trains simultaneously leaves ten Delhi and Mumbai after they metthe train travelling towards mumbai reached there after 9hours ,while train travelling towards delhi reaches after4 hours what is the speed of train running towards mumbai? Let's say an there are two objects or vehicles, both of them travel towards the same direction with constant velocities, the other object being slower than the other. With the wind, an airplane covers a distance of 2400 kms in 4 hours and against the wind in 6 hours. A plane covered a distance of 630 miles in 6 hours. The line represents their path, which is 635 km long We need to understand exactly what is happening in this problem.
On the return trip the speed was decreased by 200km/h. Cross-multiplying, 20D = 12D + 200*12 So, he covered a distance of 6 miles in 1.5 hours. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. please explain above problem. A motorcyclist has to cover a distance of 200 km to reach city b from city a. Then that of bus is ‘3-t’. So, the total distance = D + 200. At constant speed, D/12 = (D + 200)/20
TRY: … As they drive around the course, they pass each other many times. realized that she forgot to bring her books, so rushed back home at a speed of 6 miles per When A gives B a head start of 40 m he wins by 19s , therefore when A travels 1000m B travels 1000 - 40 - 19v m, where v is the speed of B. ratio of speeds of A and B = 1000 / ( 960 - 19v )..... (1), and when A gives B a headstart of 30s B wins by 40 m , therefore when A travels 960m B travels 1000 - 30v m, Ratio of speeds of A and B = 960/ ( 1000 - 30v) ..... (2), Hence time taken by B to travel 1000m = 1000/6.66 = 150s, and time taken by A to travel 1000m = 125 s. A, B, C start from the same point on a linear track and travel in the same direction at constant speeds. Without stopping at Jalna, he turned back & again encountered the bus 80 minutes after he left Aurangabad. hour. If the difference in times was 2 hours, what was the jets speed from Bangkok to Tokyo? The speed of the first car was in 10 miles per hour greater than that of the second car. At what time will Bola meet Ade assuming traveling in the same direction. She then walked back to school at a speed of 4 miles per hour. An engineer travels from St. John’s, Newfoundland, to the Hibernia oil field in the North Two persons are walking towards each other on a walking path that is 20 miles long. Time taken to cover the distance upstream + Time taken to cover the distance downstream = 3. in how hours will they be together? speed of car B= 13*3 miles / 1 hr = 39 miles/hr, Two cars P and Q start simultaneously from points A and B respectively at different speeds and travel towards each other. Two cars (A and B) start at the starting line at the same time on a 3-mile long circular track, going in opposite directions.
B) 20 kmph Let the remaining distance from the first meet to the finish be d. Now the total distance traveled by Deepak and bus in 50 min = 2d. D = 200*12/8 = 300m. What are the speeds of the two cars? .’. A) 30 kmph Solving which gives d = 60, which is the distance travelled by train.
