Answer:
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.
