In the morning, a farm worker packed 3 pints of strawberries every 4 minutes. In the afternoon, she packed 2 pints of strawberries every 3 minutes. what was the difference between her morning and afternoon packing rates in pints per hour?

To determine the difference in the number of pints packs per hour, you will use each rate and determine how many pints are packed per one hour.

3 pints every four minutes equals 45 pints per hour. (x15).

2 pints every three minutes equals 40 pints per hour (x20).

The difference is 5 pints.

The difference is an amount of 1/12 of a pint per minute.

To find the difference we need to subtract the two rates.

In the morning, the rate is 3/4.

In the afternoon, the rate is 2/3.

3/4 - 2/3

9/12 - 8/12

1/12
