Question

Pablo can wash 6 cars in 40 minutes at this rate how many cars can Pablo wash in 4 hours

Answer 1

16

Explanation:

convert 40 minutes to hours

`(40 \: minutes)/(1) * (1 \: hour)/(60 \: minutes) = (40)/(60) = (2)/(3) hour`

multiply to find the number of cars per hour

`(2)/(3) * (6)/(1) = (12)/(3) = 4 \: cars \: per \: hour`

multiply again

`4 * 4 = 16`
