Q. Lea's car travels an average of 30 miles per gallon of gas. If she spent $20.70 on gas for a 172.5 mile trip, what was the approximate cost of gas in dollars per gallon?
Calculate Gallons Used: First, we need to determine how many gallons of gas Lea used for her 172.5 mile trip. We know that her car travels 30 miles per gallon. So, we divide the total miles by the miles per gallon to find the gallons used.Calculation: 172.5 miles ÷30 miles/gallon = 5.75 gallons
Find Cost Per Gallon: Next, we need to find out the cost per gallon. We know that Lea spent $20.70 on gas for the trip. To find the cost per gallon, we divide the total cost by the number of gallons.Calculation: $20.70÷5.75 gallons = approximately $3.60 per gallon
