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?
1 wall takes 45 mem * 1 hr = 45 member hours to paint
if you have 12 memebers it will take 12 * x = 45 mem hrs
x = 45/12 = 3 3/4 hrs
It's inversely proportional
soooo
is 45 members paint a wall in 60 min, then it would take 45x12/45 members to paint 1 wall in 60x 45/12 min.
so 12 members can paint 1 wall in 225 minuutes.
tell me if I'm wrong idk
