So my son is having trouble with his homework A turtle walks 7/8 of a mile in 30 minutes what is the unit rate in miles per hour

1.75 miles per hour

Step-by-step explanation:

Turn the 7/8 into decimal form, giving you: 0.875.

Then, you take the thirty minutes and turn that into decimal form: 0.5

We want a unit rate where 1 is in the denominator, so we divide top and bottom by 0.5

That gives you 1.75 / hour.

So, your answer is 1.75 miles per hour.
