Question

A man sitting in a train which is traveling at 50 kmph observes that a goods train, traveling in opposite direction, takes 9 seconds to pass him. If the goods train is 280 m long, find its speed.?
A. 50 kmph
B. 58 kmph
C. 62 kmph
D. 65 kmph

Answer 1

relative speed=280/9=112kmph.

speed of goods train =112-50=62kmph

Answer 2

Answer:

Relative speed = 280/9 m / sec = ((280/9)*(18/5)) kmph = 112 kmph.

Speed of goods train = (112 - 50) kmph = 62 kmph
