The answer to your question is 166 mi/h
Step-by-step explanation:
Data
ve = rate eastbound train
vw = rate westbound train = ve - 14
distance = d = 900 mi
time = t = 5 h
Formula
v = 
Substitution and simplification

Now, substitute this value in the equation of vw
vw = 180 - 14
Result
vw = 166 mi/h
