All members of our painting team paint at the same rate. If 20 members can paint a 6000 square foot wall in 24 minutes, then how long would it take the 20 members to paint a 9000 square foot wall, in minutes?
It would take 6 minutes.
So the rate that your 20 members work at is 6000/24, which is 250 square feet per minute.
9000/250 = 36 minutes.
It would take 20 members 36 minutes to paint a 9000 square foot wall.
That's correct, thank you!
