All of the members of our spray-painting team paint at the same speed. If 20 team members can paint a 4800 square foot wall in 36 minutes, then how many minutes would it take for 9 team members to paint a 3600 square foot wall?

20 t * 36 m / 4800 ft^2 = .15 t m /ft^2

 

.15 t m / ft^2    *  3600 ft^2  / 9 t   =  60 min
