Answer 1

Answer:

15 minutes

Explanation:

Let the minutes spent washing a car =x

• Total minutes spent washing 5 cars = 5x

,

• Also, Sharon spent 15 minutes putting everything away.

Since it took her a total of 90 minutes, we have that:

$5x+15=90$

We then solve the equation for x.

5x=90-15

5x=75

x=75/5

x=15

It took Sharon 15 minutes to wash each car.
