Question

A car traveling on the taconic parkway travels 84 mike in two hours what is the cars speed (a special type of rate) in miles per hour?

Answer 1

we know that

the speed's formula is equal to

`speed=distance/time`

in this problem we have

`distance=84\ miles\\time=2\ hours`

Substitute the values in the formula

`speed=84/2`

`speed=42(miles)/(hour)`

therefore

the answer is

`42(miles)/(hour)`
