    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
