I drove to the beach at a rate of 40 miles per hour.  If I had driven at a rate of 32 miles per hour instead, I would have arrived 25 minutes later.  How many miles did I drive?

Distance ==D,   Time ==T

 

D / 40 ==T 

D / 32==T + 25/60, solve for D, T

 

D==200 / 3 ==66 + 2/3 miles to the beach.

T ==5/3 ==100 minutes

 

At 32 mph, it would have taken you: 125 minutes
