Question

Emily can ride her scooter 18 miles in 50 minutes.

c. What is her unit rate in miles per hour?

Answer 1

there is no miles per hour because she wasn't riding for an hour

Answer 2

22.5 miles per hour (rounded answer)

Explanation:

This is a fraction equal to

18 miles ÷ 0.8 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 0.8

18 miles ÷ 0.8

0.8 hours ÷ 0.8

=

22.5 miles

1 hour

=

22.5 miles

hour

= 22.5 miles per hour
