Question

Etrain of your length 50 M is moving with a constant speed of 100 metre per second the time taken by the trying to cross a bridge of length 150 M is dash seconds

Answer 1

the answer is 1 second because 150-50=100m,so the time taken is 1 second

Answer 2

Distance travelled to cross the bridge completely is 150 m + 50 m = 200 m

Time = Distance / Speed
= 200 m / (100 m/s)
= 2 seconds

Train will cross the bridge completely after 2 seconds
