And ice cream factory makes 120 quarts of ice cream in 10 hours. How many quarts could be made in 12 hours? What was that rate per day?

My answer is 144 quarts are made in 12 hours.

I first found out how many quarts are made in 1 hour.

120 divided by 10 is 12.

12 quarts are made per hour.

So apply this to 12 hours.

12 times 12 = 144 quarts.

144 hours because 120 divided 10 is 12, 12 times 2 is 24, 24 plus 120 is 144 then add on the label and you get 144 hours!
