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?

Tonya

Freda

39 mi

52x

65x

One way to look at it might be to say

52x + 39 = 65x

Or another way might be to say 65x – 52x = 39

Both are correct and will give you the correct answer of
