Question

Jesus can wash 6 cars in 40 minutes. At this rate, how many cars can Jesus
wash in 4 hours?

Answer 1

36

Explanation:

4 hours * (60 minutes)/(1 hour) = 240 minutes

We can use a proportion.

6 cars : 40 minutes = x cars : 240 minutes

6/40 = x/240

3/20 = x/240

20x = 3 * 240

x = 3 * 12

x = 36

Answer: 36
