```										T = distance/speed =  120/v    (initial time)
final time = 240/2v = 120/v     (final time)
therefore time will remain same ......

```										We know,
s=ut+1/2 at2
but since the train is going with uniform velocity, hence the acceleration is zero.
therefore,
s=ut
In the first case,
120=vt
t=120/v
In the second case,
240=2vt
t=120/v

Hence, the time in both the cases, time taken will be the same.
