Answer 1

Step-by-step explanation:

If train-A has to cross the train-B the distance traveled by A will be the sum of the length of the trains A and B= 100+120=220m = 0.22km Sice the trains are traveling in the opposite directions, the relative speed of train A will be the sum of the speed of A and B = (50 + x) kmph
