Answer: Sam's rate = 10.35 miles per hour.
Step-by-step explanation:
Given, Distance covered by Sam = 63,756 feet
In miles, Distance = [tex]\dfrac{63756}{5280}= $12.075\ miles[/tex] [1 mile = 5280 feet]
Time taken = 70 minutes
In hour , time =[tex]\dfrac{70}{60}=\dfrac{7}{6} \ hr[/tex] [ 1 hour = 60 minutes]
Sam's rate = [tex]\dfrac{Distance}{Time}[/tex]
[tex]=\dfrac{12.075}{\dfrac76} \\\\\dfrac{12.075}{7}\times6=\\\\= 10.35\ \text{ miles per hour}[/tex]
Hence, Sam's rate = 10.35 miles per hour.
