Question

Sally ran 2 1/4 miles in 1/2 hour. What is her speed in miles per hour?

Answer 1

Explanation:

2 1/4 = 2.25 miles

1/2 hour = 30 minutes

30 minutes x 2 = 1 hour

2.25 x 2 = 4.5 miles

Sally runs 4.5 miles per hour.

Hope this helps!

Answer 2

5 miles per hour ;)
Just multiply by 2 to get 5 miles in 1 hour
