Question

Janice can ride her bike 4 miles in 30

minutes. Sam can ride his bike 3 miles in
24 minutes. At his current rate, what is
the distance, in miles, Sam can ride his
bike in 1 hour?

Answer 1

I believe it would be 7.5 miles in one hour.

Explanation:

Write the problem out as a proportion. Divide 60 by 24. This is 2.5, so you then multiply the 3 miles by 2.5. There's your answer! :)

24 Minutes 60 Minutes

------------------- = ------------------

3 Miles (x2.5) 7.5 Miles
