Answer:

324 minutes or 5.4 hours

Step-by-step explanation:

400/3 = 133.333

133.333/60 = 2.2222

It took him one minute to paint 2.2222 square feet

720/2.2222 = 324 minutes

324/60 = 5.4 hours

Answer:

It will take Andy 5 hours and 24 minutes to paint 720 sq. ft.

Step-by-step explanation:

Since he painted 400 sq. ft. in 3 hours, then do 400/3 to get 133.33... sq. ft per hour. Then, do 720 / 133.33... to get 5.40000000001 hours taken. The 5 represents 5 hours, and the .4 represents 24 minutes (because 60 x .4 = 24).

Overall, you get 5 hours and 24 minutes of time to pain 720 sq. ft.

You first need to convert the fractions so they are both eighths.

1 3/4 = 1 6/8

Then you simply need to add:
1 6/7 + 3 3/8 = 4 9/8 = 5 1/8

Your answer is 5 1/8.
