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?

Respuesta :

Answer:

5 pints per hour.

Step-by-step explanation:

Morning:

Given:

Number of strawberries packed in every 4 minutes = 3

∴ Number of strawberries packed in every one minute = [tex]\frac{3}{4}[/tex]

So, number of strawberries packed in every 60 minutes = [tex]\frac{3}{4}\times 60=45[/tex]

1 hour = 60 minutes.

So, strawberries are packed at a rate of 45 pints per hour in the morning.

Afternoon:

Number of strawberries packed in every 3 minutes = 2

∴ Number of strawberries packed in every one minute = [tex]\frac{2}{3}[/tex]

So, number of strawberries packed in every 60 minutes = [tex]\frac{2}{3}\times 60=40[/tex]

1 hour = 60 minutes.

So, strawberries are packed at a rate of 40 pints per hour in the afternoon.

Difference between the packing rates is given as:

Morning rate - Afternoon rate = 45 - 40 = 5 pints per hour.

So, she packed 5 more pints in one hour in the morning than in the afternoon.
