George can box 36 packs of 12 doughnuts, per hour. What is George's rate for 720 doughnuts?

1.5 hours.

Step-by-step explanation:

First find out how many doughnuts he packages and hour which is 472

(36 x 12)

Then divide 720 by 472 which is about 1.5 so it would take about an hour and a half to package 720 doughnuts which would come out to 60 packages all together.

(720 / 12 = 60)
