Question

Sal washed 5 cars in 50 minutes. What is the unit rate?

Answer 1

10 mins / car

Explanation:

50 / 5 = 10

Answer 2

since Sal washed 5 cars in 50 minutes, we can express his time as follow:

`(5 \: cars)/(50 \: minutes)`

simplifying it by diving by 5, we get:

`(1 \: car)/(10 \: minutes)`

Thus the rate will be 10 minutes per car (10 min/car)
