Since the two trains are passing in opposite directions, so this means that their relative velocities will be the sum of the two trains that is:

relative velocity = (13 + 28) = 41m/s

a. The passengers aboard on train B will see that train A is moving at 41m/sec due east

b. The passengers aboard on train A will see that train B is moving at 41m/sec due west
