Answer 2

`Rate = (320\ miles)/(4\ hours)`

`Rate = 80\ miles/hour`

Explanation:

Given

`Distance = 320\ miles`

`Time = 4\ hours`

Solving (1): Determine the rate.

Rate, in this case is:

`Rate = (Distance)/(Time)`

`Rate = (320\ miles)/(4\ hours)`

Solving (2): Simplify the denominator to 1

`Rate = (320\ miles)/(4\ hours)`

Divide numerator and denominator by 4

`Rate = (320/4\ miles)/(4/4\ hours)`

`Rate = (80\ miles)/(1\ hour)`

`Rate = 80\ miles/hour`
