Question

A train of length 100 m is moving with constant velocity of 20m/s.find the time taken by the train to cross a bridge of length 100m?

Answer 1

I hope you can understand the answer

Answer 2

Total distance required for the train to cross the bridge is,

d = (100 + 100) m = 200 m

Hence the time taken to cross the bridge is,

t = 200 / 20 = 10 s.
