Tonya and Freda drive away from Norfolk on the same road in the same direction. If Tonya is averaging 52 mph and Freda is averaging 65 mph, how long will it take for them to be 39 miles apart?

We let x stand for the time they have been driving which would be the same in this case.  How far they have gone (distance) is written in the chart by using the known information and the formula R*T=D
