Marta traveled m miles at a miles per hour, and Kristel traveled the same distance but at a slower rate of b miles per hour. What is the difference in hours between the times of the two girls?
D/R = T........let D = the distance
And Marta's time = D/m
And Kristel's time = D/b
So.....the difference in the times is just
D/m - D/b =
[Db - Dm] / [mb]
Haha, well that was an obvious answer, I should have known that one. Thank you very much.
