Question

A train of length 100 metre long moving with speed 20 metre per second on a bridge of length 100 metre then the time taken to cross a Bridge is is

Answer 1

Answer:

=Speed = 20m /s

=Distance/ time = 20m/s

=Time =100m/(20m/s)

=5 s

Thus, time taken to cross the bridge is 5s.

Correct me if I'm wrong.

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.
