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.
