Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 14 miles per hou
Sergeu [11.5K]

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 = \frac{distance}{time} = \frac{d}{t}

Substitution and simplification

ve = \frac{900}{5} = 180 mi/h

Now, substitute this value in the equation of vw

vw = 180 - 14

Result

vw = 166 mi/h
