Answer:
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 = [tex]\frac{distance}{time} = \frac{d}{t}[/tex]
Substitution and simplification
[tex]ve = \frac{900}{5} = 180 mi/h[/tex]
Now, substitute this value in the equation of vw
vw = 180 - 14
Result
vw = 166 mi/h
