Answer:
7 1/2 miles
Step-by-step 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 :)
