Answer:
105 m/s
Explanation:
Given that the speed of train A,  = 45 m/s from west to east.
 = 45 m/s from west to east.
Speed of train B,  = 60 m/s from east to west.
 = 60 m/s from east to west.
Train B is moving in the opposite direction with respect to the speed of train A. Assuming that the speed from east to west direction is positive.
So, the speed of train A from east to west= - 45 m/s
The speed of train B w.r.t train A  m/s
 m/s
Hence, the speed of train B w.r.t train A is 105 m/s from east to west.
