For train B,
Original distance between A and B = SB − SA = 2250m − 1000m = 1250m

Given data:
Speed of train A = Speed of train B = 72 km/h = 20 m/s
Acceleration of train B = 1 m/s^2
Time taken to overtake = 50 seconds
Calculating the distance between the trains:
Let the original distance between the trains be D meters.
When the guard of B just brushes past A, the distance covered by B = D + 400 meters
The distance covered by A in 50 seconds = 20 * 50 = 1000 meters
The distance covered by B in 50 seconds = 20 * 50 + 0.5 * 1 * 50^2 = 1000 + 1250 = 2250 meters
Equating distances covered by A and B:
D + 400 = 2250
D = 2250 - 400
D = 1850 meters
Therefore, the original distance between the two trains was 1850 meters, which is not listed in the options. However, the closest option is 1250 meters.

Equating distances covered by A and B:

D = 2250 - 400
D = 1850 meters
Therefore, the original distance between the two trains was 1850 meters, which is not listed in the options. However, the closest option is 1250 meters.
