Question

Laurnen can jog 1 1/2 miles in 1/5 of an hour. What is the unit rate in miles per hour?

Answer 1

7 1/2 miles

Explanation:

These step are going to be in ratios.

Step 1: figure out how to write down the ratio, in this, like ____unit per ______ unit.

1 1/2 miles per 1/5 of an hour, or 1 1/2 / 1/5

Step 2: In order to do miles for just a whole 1 hour, you would need to multiply by the reciprocal for 1/5, which would be like this:

1/5*5/1 = 1

Then, you need to multiply miles by 5/1 (or 5)

1 1/2*5= 7 1/2

and now your unit rate for miles per hour is 7 1/2 miles per hour :)
