Two trains are moving in the same direction at 72 kmph and 36 kmph. The faster train crosses a man in the slower train in 27 seconds. Find the length of the faster train?

Answer»

270 m

Relative speed = (72 - 36) * 5/18 = 2 * 5 = 10 mps.

Distance covered in 27 sec = 27 * 10 = 270 m.

The LENGTH of the faster TRAIN = 270 m.
