Answer 1

Thank you for posting your question her at brainly. Below are the choices that can be found elsewhere:

A. 1.6 m/s north 
B. 2.2 m/s south. 
C. 2.2 m/s north. 
D. 5.4 m/s north. 

The answer is letter A which is 1.6 m/s north. Below is the solution:

1.6 m/sec N - relative to the train 
(1.6 m/sec N) + (3.8 m/sec N) = 5.4 m/sec N
