Here two conditions are forming my friend
1st train equally parallel another is one train is just behind the other train on parallel track and commonly it is found to second condition
Now see Your answer take it is as
Relative velocity of two train will be 50-45 as they moving in same direction
Rv= 5km/hr
total distance the second train has to cover while overtaking it by its tail side is equal to sum of length of two train i.e 100m
now time taken can be calculated by simple formula of speed =distance/time
t= 0.1km /5= 0.02 hr
