Question

A train 180 m long moving at the speed of 20 m/sec overtakes a man moving at a speed of 10 m/sec in the same direction. The train passes the man in?

Answer 1

Answer:

Time taken must be 18 sec

Explanation:

Given speed of train = 20m/s

Speed of man = 10m/s

So,

Net speed of train with refrence to man = 20 - 10 m/s

= 10 m/s

So, to travel a distance of the length of traon i.e, 180 m, time taken = Total distance /Net speed = 180 /10 = 18sec
