Answer:
372 miles
Step-by-step explanation:
The relationship between speed, distance, and time is ...
distance = speed × time
Separation speed
The vehicles are traveling in opposite directions, so their speed of separation is the sum of the individual vehicle speeds:
separation speed = (65 mi/h) +(59 mi/h) = 124 mi/h
Distance
Then the separation distance after 3 hours is ...
separation distance = separation speed × time
= (124 mi/h)(3 h) = 372 mi
After 3 hours, the vehicles are 372 miles apart.
