Question

All of the members of our spray-painting team paint at the same speed. If 20 team members can paint a 4800 square foot wall in 36 minutes, then how many minutes would it take for 9 team members to paint a 3600 square foot wall?
thanks ! :)

Answer 1

Answer:

60 minutes

Step-by-step explanation:

How fast can one team member paint?

20 * 36 = 720 minutes

One team member can paint a 4800 square wall in 720 minutes.

How fast can one team member paint a square wall of 3600 square feet?

720 * (3600/4800) = 540 minutes

Now how fast would it take 9 team members?

540 / 9 = 60 minutes.
