You can put this solution on YOUR website! Think of one car as standing still and the other as
traveling at the difference of their speeds.
the distance from the moving car and the stationary car
is mi
Let = time in hours when the distance between
the moving car and the stationary car
is mi
----------------------
In 6 hrs they will be 84 mi apart
