Answer:
Question 1:
5 pints per hour
Question 2:
480 tons per day
Question 3:
12 miles per gallon of gasoline
Step-by-step explanation:
Question 1:
In the morning;
A farm worker packed 3 pints of grapes every 4 minutes.
1 minute = [tex]\frac{1}{60}[/tex] hours
Packing rate in pints per hour = 3 pints ÷ [tex]\frac{4}{60}[/tex] hours = 45 pints per hour
In the afternoon;
She packed 2 pints of grapes every 3 minutes.
Packing rate in pints per hour = 2 pints ÷ [tex]\frac{3}{60}[/tex] 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
Question 2:
A recycling plant processes an average of [tex]\frac{1}{3}[/tex] tons of glass each minute.
1 hour = 60 minutes
The number of tons of glass processed in 1 hour is:
[tex]\frac{1}{3}[/tex] × 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
Question 3:
A vehicle uses 1[tex]\frac{1}{8}[/tex] gallons of gasoline to travel 13[tex]\frac{1}{2}[/tex] miles.
Per 1 gallon of gasoline the vehicle will travel:
1 × 13[tex]\frac{1}{2}[/tex] ÷ 1[tex]\frac{1}{8}[/tex] = 12 miles
