Hello!
The thing you have to do here is get the miles per hour, which means we have to multiply the 1/15 by 15 to get 15/15, which is 1.

When you do this, you should also multiply the 3/5 miles by 15, which is 45/5 or 9.

This means the rate is 9 miles per hour 

Hope this helped you!

The dog runs 3/5 miles in 1/15 hour - that's 4 mins

To find out how many miles in an hour, simply multiply 3/5 by 15 (to make a whole hour).

3/5 x 15 = 9 miles an hour
