Question

Mitch and Delilah both drove 500 miles. Mitch averaged 60 miles per hour. Delilah averaged 65 miles per per hour. How muc longer than Delilah did it take Mitch to drive 500 miles?

Answer 1

First, we need to figure out how long it took Delilah to travel 500 miles.  We can do this by dividing 500 by 65.  This is equal to 7.69 hours, or 7 hours and 41 minutes.

Next, we figure out how long it took Mitch to drive 500 hours.  We do this the same way: divide 500 by 60.  500/60 = 8.33 hours, or 8 1/3 hours.

We finish this problem by subtracting 7.69 from 8.33.  This is equal to 0.64 hours, or 38 minutes.  So, it took Mitch 0.64 hours or 38 minutes longer than Delilah to drive 500 miles.
