The mileage of Alyssa's car is a measure of how far the car has traveled per unit fuel.
The best method and reasoning to calculate the gas mileage is:
D. 243.8 miles ÷ 7.71 gallon s
because dividing a quantity with units of miles by a quantity with units of gallons gives a quantity with units of miles per gallon.
From the complete question, we have:
[tex]Miles\ Traveled = 243.8[/tex]
[tex]Gallons\ Used = 7.71[/tex]
The mileage of the car is calculated by dividing the number of miles traveled by the amount of gas used.
So, we have:
[tex]Mileage = Miles\ Traveled \div Gallons Used[/tex]
This gives:
[tex]Mileage = 243.8 \div 7.71[/tex]
From the given parameters;
The unit of miles traveled is miles
The unit of gallons used is gallons
Because the miles traveled is divided by the gallons used, then the unit of the mileage would be miles per gallon
Hence, the correct method and reasoning is (D).
