Question

Mike drove 8 miles in a `1/4` hour. What is his unit rate in miles per hour?

Answer 1

32 miles per hour.

Explanation:

If Mike drives 8 miles in 15 minutes, or `1/4` of a mile, to find the unit rate per hour, we would have to to multiply 15 by four, which is 60 minutes, or 1 hour. We would also have to multiply 8 by 4, which is 32. Thus, Mike drove 32 miles per hour.
