T = D/S ; where T = time taken, D = total distance and S= speed.
Total distance will be the lengths of both trains put together, which is 2km
Because the trains are traveling in the opposite directions, the net relative speed will be 150km/hr.
Inputting these values in the equation T = D/S will give you T = 48 seconds.
Hence our answer is C
