Relative velocity of overtaking is the difference of the speed with whihc the trains are moving. That is 
Relative velocity = 40 m/s - 30 m/s = 10 m/s

In order to overtake, the first train has to cover a distance of the sum of the lengths of both the train.
That is the total distance covered with this relative velocity during overtaking will be = 100 m + 200 m = 300 m
