1.

A Man Sitting In A Train Which Is Travelling At 50 Kmph Observes That A Goods Train, Travelling In Opposite Direction, Takes 9 Seconds To Pass Him. If The Goods Train Is 280 M Long, Find Its Speed?

Answer»

Relative Speed = (280 / 9) m/sec

= (280/9 x 18/5)

= 112 KMPH.

Speed of the train = (112 - 50) kmph

= 62 kmph.

Relative Speed = (280 / 9) m/sec

= (280/9 x 18/5)

= 112 kmph.

Speed of the train = (112 - 50) kmph

= 62 kmph.
