Question

Willie runs 3 miles in 21 minutes. If Willie runs at the same rate, how many miles can he run in 63 minutes?

Answer 1

Since Willie runs 3 miles in 21 minutes, his rate is 3 miles / 21 minutes = 0.142857 miles per minute.

To find out how many miles he can run in 63 minutes, we multiply his rate by the number of minutes:

0.142857 miles/minute x 63 minutes = 9 miles

Therefore, Willie can run 9 miles in 63 minutes.
