Question

If it takes someone t minutes to drive run or walk a mile then their averages speed

Answer 1

EXPLANATION

Since the average speed is given by the equation:

`s(t)\text{ = }(60)/(t)`

Computing s(10) and s(12):

`s(10)\text{ = }(60)/(10)=6`

Now, computing s(12):

`s(12)=(60)/(12)=5`

In conclusion, the solutions are:

s(10) = 6 miles per hour

s(12) = 7 miles per hour
