Comments: I have tried so much to solve this but it is so hard. I came up with a formul: distance/time=rate. I got 10 minutes for A but I know it's wrong. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 10 miles/60 miles/hour=1/6 hours to work=10 minutes.
---------------------------
10 miles in 5 minutes= 10 miles in 1/12 hour
12 x 10= 120 mph
120 mph x 1/12 hour=10 miles.
----------------------
10 miles in 2.5 minutes=
60/2.5 x 10=24 x 10 miles=240 mph.
------------------
rate x time=distance
distance/time=rate..
