All members of our painting team paint at the same rate. If $50$ members can paint a $3600$ square foot wall in $20$ minutes, then how long would it take for $25$ members to paint a $4000$ square foot wall, in minutes?

We know that 50 members can paint a 3600 square foot wall in 20 minutes.

25 members will take twice as much time because the number of members is halfed, so 25 members can paint a 3600 square foot wall in 20 x 2 = 40 minutes. To paint a 4000 square foot wall, 25 members will paint the wall in 40 x 4000/3600 = 40 x 1.11111 ≈ 44.4 or 44 minutes.

 

Answer: 44 minutes
