<u>Question 2:</u>

<u>Question 3:</u>
12 miles per gallon of gasoline
<u />
Step-by-step explanation:
<u>Question 1:</u>
<h2><em>In the morning;</em></h2>A farm worker packed 3 pints of grapes every 4 minutes.
1 minute = hours
Packing rate in pints per hour = 3 pints ÷ hours = 45 pints per hour
She packed 2 pints of grapes every 3 minutes.
Packing rate in pints per hour = 2 pints ÷ hours = 40 pints per hour.
The difference between her morning and afternoon packing rates (in pints per hour) = 45 pints per hour - 40 pints per hour = 5 pints per hour
<u>Question 2:</u>
A recycling plant processes an average of tons of glass each minute.
1 hour = 60 minutes
The number of tons of glass processed in 1 hour is:
× 60 = 20 tons of glass in 1 hour.
1 day = 24 hours
Number of tons of glass processed in a day = 20 tons × 24 = 480 tons
<u>Question 3:</u>
A vehicle uses 1 gallons of gasoline to travel 13
miles.
Per 1 gallon of gasoline the vehicle will travel:
1 × 13 ÷ 1
= 12 miles
