All members of our painting team paint at the same rate. If $45$ members can paint a specific wall in $60$ minutes, then how long would it take $12$ members to paint the same wall, in minutes?
We know that 45 members can paint a wall in 60 minutes, so we can find out that 12 members can paint the same wall in 60 x 45/12 = 60 x 3.75 = 225 minutes.
