After solving where get the value of x in km/hr. find the speed of the train going in the opposite direction if its length is 75m. Please give an appropriate answer with perticular reason, this is not clear to me. @Karthika , see when we take the series 220/5x+250/18=6 than the 18 will go up side and new series came 220*18/5x+250=6 , so here the formula 18/5 km/h is applicable . Hence, the son of lady's brother is brother-in-law of the person. Relative speed = (x + 50) km/hr = (x + 50) x: 5: m/sec: 18 = 250 + 5x: comics © PIXTON.COM. C. 54 km/hr. Score Well In SBI & IBPS, PO & Clerk Exams.
The length of the wire is??? The angle of elevation of the sun, when the le... 14. Find the speed of the second train? I would like to bring this error to your notice that it is 82 m/s and not 82 km/hr. a)5 seconds b)3 seconds c)7 seconds d)6 seconds, speed of the train = 120 km/hr = 120 x5/18 m/sec = 100/3 m/sec, Distance covered in passing the long wall = (80+150) = 230 m, Time taken to cross the wall = 230 x 3/100 = 6.9 sec, Hence the answer is 7 seconds(approximately).
