Maggie and Jenna both leave the library at the same time, but in opposite directions. If Jenna travels 7 mph faster than Maggie and after 9 hours they are 225 miles apart, how fast is each traveling?

Answer 1

Jenna went 16 mph, Maggie did 9 mph

9(M+7) + 9M = 225

9(2M+7) = 225

2M + 7 = 225/9 = 25

2M = 18

M = 18/2 = 9

J = 9+7 = 16
