Two trains of equal length running in the same direction at 46 km/h and 36 km/h cross each other in 36 seconds. The length of each train (in metres) is:

Question

Accepted Answer

50. Same direction → relative speed = 46 − 36 = 10 km/h = 25/9 m/s. Distance covered = (25/9) × 36 = 100 m, which equals the combined length 2L. So L = 50 m.
