Answer :

The number of minutes it would take for 9 team members to paint a 3600 square foot wall is 90 minutes.

How to find the number of minutes?

2400/540 = 4.44 sq / ft per man-minutes

Now let find the minutes it would take paint a 3600 square foot wall

let m represent the number of min for 9 men to do 3600 sq/ft

3600/4.44 = 810 man-min

9m = 810

m = 810/9

m = 90 minutes
