Two trains A and B of length 400 m each are moving on two parallel tracks with a uniform speed of 72 Km/h in the same direction, with A ahead of B. The driver of B decides to overtake A and accelerates by 1 m/s. If after 50 s, the guard of B just brushes past the driver of A, what is the original distance between them?   1250 m   150 m   50 m   125 m
