We are trying to find miles/hour, which shows that we are going to be dividing the total number of miles by the total number of hours. Thus, in this case, the miles/hour rate will be:
[tex]\dfrac{800 \,\textrm{miles}}{20 \,\textrm{hours}} = 40 \dfrac{\textrm{miles}}{\textrm{hour}}[/tex]
He drove 40 miles in one hour.
To find the rate you do 800miles divided by 20 hours. Which is 40 miles
