You can put this solution on YOUR website! Two cars leave Pima Community College traveling in opposite directions. One car travels at 80 mph and the other at 54 mph. In how many hours will they be 938 miles apart?
-------------
1st Car DATA:
rate = 80 mph ; time = x hrs. ;distance = 80x miles
-----------------
2nd Car DATA:
rate = 54 mph ; time = x hrs. distance = 54x miles
--------
Equation:
dist + dist = 938 miles
80x + 54x = 938
134x = 928
x = 7 hrs.
