Question

an ice cream factory makes 290 quarts of ice cream in 5 hours how many quarts could be made in 12 hours ? what was the rate oer day

Answer 1

696 qt in 12 hours

1392 qt per day

Explanation:

Use a proportion.

(290 qt)/(5 hr) = (x)/(12 hr)

5x = 290 * 12

5x = 3480

x = 696

Answer: 696 qt in 12 hours

A day has 24 hours, 696 * 2 = 1392

Answer: 1392 qt per day

Answer 2

You would use a proportion to answer both questions.

First we set up a ratio of 100 quarts:5 hours since that is a given ratio. Since hours was in the denominator of the ratio before, we place the 36 in the denominator of the other ratio, x quarts: 36 hours.

Setting them equal gives the following proportion:

100/5=x/36

Cross multiply to solve:

5x=3600

x=720

They can make 720 quarts in 36 hours.

For the second part, we use similar reasoning. Remember 1 day = 24 hours.

100/5 = x/24

5x =2400

x=480

They can make 480 quarts per day.

just substitute values to find answer
