All members of our painting team paint at the same rate. If $10$ members can paint a $100$ square foot wall in $10$ minutes, then how long would it take the $15$ members to paint a $100$ square foot wall, in minutes?

100 ft^2  / ( 10 m * 10 p) =    1 ft^2 / 1 m - p          each square foot requires 1  people  minute 

 

100 ft^2    * 1 p m / ft^2    /  15 p   =  6  2/3 minutes
