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 4200 square foot wall?

20t x 36m / 4800 ft2     =    .15  t-m /ft2

.15 t-m /ft    x  4200 ft2  /9  = 70 minutes
