Question

Ratio Ralph can ride his bike 5 miles in 20 minutes. How many miles can he ride in

an hour and a half if he keeps this pace?

Answer 1

22.5 miles

Explanation:

There are 3, 20 minute increments in an hour, and 1 and a half 20 minute increments in half an hour, so, you simply add 3 + 1.5 which equals 4.5.

Then, multiply 5 (miles) by 4.5 to get 22.5 (miles).
