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.
