Answer
390 minutes
Work Step by Step
We are given the distance (d) of the race course as 65 miles. We are given the rate or speed (r) as 10 mi/h. We need to find time (t). We can use the formula d=rt to find the time. Lets substitute the variables into this equation.
65=10$\times$t (Divide both sides by 10)
6.5 hours = t
It asks us to find the time in minutes. We know that 1 hour = 60 minutes so we can multiply our time in hours by 60 to get the time in minutes.
6.5 $\times$ 60 = 390.
So our answer is 390 minutes.
