Question

Two trains each 50 metre long are travelling in opposite directions with velocity 10 metre per second and 15 metre per second the time of crossing is

Answer 1

Answer:

Both are moving in opposite direction so, their relative velocities of both train became 25 m/s means train velocity now taken as 25 m/s. As both train are 50 m long…they have to travel 100m to cross each other.

So by equation,

Time= distance/velocity

Time= 100/25

Answer= 4 seconds
