Answer:
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)
George's rate is 240 packs for 1 doughnut, per hour if George can box 36 packs of 12 doughnuts, per hour.
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
George can box 36 packs of 12 doughnuts per hour
Also, the rate can be defined as the change in values of a dependent variable with respect to the independent variables.
36 → 12 doughnuts per hour
Let x be George's rate for 1 box
1 → x
36/1 = 12/x
x = 12/36
x = 1/3 doughnuts per hour
For 720 doughnuts:
The George's rate for 720 doughnuts
= (1/3)720
= 240 packs for 1 doughnut, per hour
Thus, George's rate is 240 packs for 1 doughnut, per hour if George can box 36 packs of 12 doughnuts, per hour.
