Answer: It would take 9 hours for 4 painters to paint 720 feet of fence.

Step-by-step explanation:

1.) Calculate the time needed to paint the 720 ft fence with 2 painters.

    a.) Divide 720 by 280 to get how many times greater 720 is than 280.

         720 / 280 ≈ 2.57

    b.) Multiply the time needed to paint the 280 ft fence with 2 painters by 2.57.

         7 * 2.57 ≈ 18

2.) Calculate the time needed to paint the 720 ft fence with 4 painters.

   a.) Assuming that each painter paints the same amount of fence, divide the time in half, as 4 painters is double the original amount, so it would take half of the time.

       18 / 2 = 9
