If one man can paint an eight feet by twelve feet wall in a half hour how long would it take 3 men to paint a wall that is eight feet by twenty four feet?
Area of the small wall = 8' x 12' = 96 square feet
One man can paint it in 1/2 hour, meaning one man paints 2 x 96 = 192 square feet per hour.
Three men paint 3 x 192 = 576 square feet in an hour.
Area of the large wall = 8' x 24' = 192 square feet.
If the three men split up the job, and are careful not to step on each other
or paint the same piece more than once, they can cover the large wall in
192/576 = 1/3 of an hour = 20minutes.
