Final answer:
To calculate the miles per gallon, divide the miles driven (200 miles) by the gallons of fuel used (10 gallons), resulting in 20 miles per gallon. The operation used is division.
Step-by-step explanation:
To compute the miles per gallon for a car that drove 200 miles using 10 gallons of fuel, you would use division. Miles per gallon is calculated by dividing the number of miles driven by the number of gallons used. In this case, you would divide 200 miles by 10 gallons, which gives you 20 miles per gallon. Therefore, the operation to use is D Division.
To compute the miles per gallon, which is 20, we need to divide the miles driven by the gallons of fuel used. In this case, the car drove 200 miles using 10 gallons of fuel, so we divide 200 by 10.
Therefore, the operation that should be used to compute the miles per gallon is Division.
