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?

10* 10  = 15 * x

 

100 / 15  =  x  =   20 / 3  min =   6 + 2/3 min  = 6 min 40 sec
