Question says that Mr. Ford drove 215 miles in 3.5 hours. Now we have to find about what is the unit rate for Mr. Ford’ s drive. that means we have to find the speed of driving.
To find the speed we can use the following formula :
[tex]Speed=\frac{Distance}{Time}[/tex]
Where Distance covered is 215 miles
and time taken to cover that distance is 3.5 hours.
Then we get speed:
[tex]Speed=\frac{215}{3.5}[/tex]
[tex]Speed=61.4285714286[/tex]
Hence final answer is approx 61.43 miles per hour.
