Alyssa wants to know the gas mileage of her new car. She kept track of the number of miles she traveled and the number of gallons she used. Which method and reasoning can Alyssa use to calculate the gas mileage in miles per gallon?Miles Traveled : 243.8Gallons Used : 7.71A. 243.8 miles × 7.71 gallonsbecause multiplying a quantity with units of miles by a quantity with units of gallons gives a quantity with units of miles per gallon.B. 243.8 miles - 7.71 gallons because subtracting a quantity with units of gallons from a quantity with units of miles gives a quantity with units of miles per gallon.C. 7.71 gallons ÷ 243.8 milesbecause dividing a quantity with units of gallons by a quantity with units of miles gives a quantity with units of miles per gallon.D. 243.8 miles ÷ 7.71 gallonsbecause dividing a quantity with units of miles by a quantity with units of gallons gives a quantity with units of miles per gallon.
