Question

In the morning, a farm worker packed 3 pints of berriesevery 5 minutes. In the afternoon, she packed 4 pints ofberries every 6 minutes. What was the differencebetween her morning and afternoon packing rates inpints per hour?

Answer 1

Given:

The worker packed 3 pints every 5 minutes in the morning and 4 pints every 6 minutes.

To find the difference in pints per hour, let's find the hourly rate for both morning and afternoon.

Hourly rate in the morning is:

`(3)/(5)*(60\min )/(1hr)=(180)/(5)=\text{ 36 pints per hour}`

Hourly rate in the afternoon:

`\frac{4\text{ pints}}{6\text{ mins}}*(60\min s)/(1hr)=(240)/(6)=40\text{ pints per hour}`

The differnce between her morning and afternoon packing rates in pints per hour will be:

`36\text{ - 40 = -4 (pints per hour)}`

The differnce is 4 pints per hour

ANSWER:

4 pints per hour
