Two vehicles leave a gas station at the same time. One travels east at 60 miles per hour, the other travels west at 30 miles per hour. In how many hours will they be 150 miles apart?
-----------------------
The cars are separating at the rate of (60+30) = 90 mph
---
time = distance/rate
time = 150/90 = 15/9 = 5/3 = 1 2/3 hrs
time = 1 hr 40 minutes
