Chan and Mieko drove separate cars along the entire length of a certain route. If Chan made the trip in 15 minutes, how many minutes did it take Mieko to make the same trip?

(1) Mieko’s average speed for the trip was 3/4 of Chan’s average speed.
(2) The route is 14 miles long.

Distance= Rate x time
Chan --> Rc x 15 = D
Mieko -->Rm x t =D

Statement A
(1) Mieko’s average speed for the trip was 3/4 of Chan’s average speed.

Rc x 15 = 3/4rRc x t --> we can solve to find mieko's time

2) The route is 14 miles long.[/quote] -->we can't say nothing about mieko's average speed and thus about its time
