Question

~Medal+Fanning~
Two cars leave town going in opposite directions. One car is traveling 50 miles per hour (mph), and the other car is traveling 40 mph. How long will it take before the cars are 360 miles apart?

4 hrs

6 hrs

2 hrs

5 hrs

Answer 1

Car A is traveling 50 miles every hour, and car B is traveling 40 miles every hour.
Add the two together, and you get a distance of 90 (more) miles apart every hour.
Since the question asks how long it takes to get the cars 360 miles apart, you just divide 360 by 90, which gets you 4 hours (choice a).
