Question

It takes 2 people 20 minutes to install 8 tires on 2 vehicles. How may tires can 4 people load in one hour?

Answer 1

Answer: 72

Step-by-step explanation:

First, multiply the amount of tires and vehicles by 3, because that would make it 2 people and 1 Hour. then, multiply the amount of people by 2. Since we have twice the people, we have twice the tires and vehicles.

Answer 2

4 people can install four times as many tires as 1 person, so they can install 12 x 4 = 48 tires in 1 hour.
