Question

A 200 metre long train is moving with velocity 20 metre per second the time taken by the train to cross a bridge of length 200 metre is

Answer 1

Answer:

200/20 = 10secs

Explanation:

distance = speed × time

Answer 2

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

d = (200 + 200) m = 400 m

Hence the time taken to cross the bridge is,

t = 400 / 20 = 20 s.
