Answer:
Unit rate of 50 miles per hour.
Explanation:
We know that the car can travel 100 miles in 2 hours.
We can divide the 100 miles by how many hours there are to make it "per hour".
Showing you so it makes more sense...
100/2 = 100 ÷ 2
= 50
Double checking because why not...
50 x 2 (hours) = 100
Hope this helped. :)
