Question

Writing Ann's car can go 210 miles on 6 gallons of gas. During a drive last weekend. Ann used 7 gallons of gas. How far did she drive? Use pencil and paper. Explain how the problem changes if you were given the distance Ann drove last weekend instead of how much gas she used She drove _____miles.

Answer 1

Ann's car can go 35 miles per gallon, so on 7 gallons, she would be able to drive 245 miles. If the distance were given instead, the problem would require calculating the gasoline consumed based on the car's mileage.

Step-by-step explanation:

To solve how far Ann's car can drive on 7 gallons of gas, given it goes 210 miles on 6 gallons, we first need to determine the car's gas mileage. We do this by dividing the number of miles she can drive by the gallons of gas used. In this case, it's 210 miles / 6 gallons = 35 miles per gallon. With that information, we can find out how far Ann can go on 7 gallons by multiplying the gas mileage by the number of gallons used: 35 miles/gallon × 7 gallons = 245 miles. Ann drove 245 miles last weekend.

If we were given the distance Ann drove instead of how much gas she used, the problem would involve finding out the amount of gasoline consumed. We would divide the distance traveled by the car's gas mileage to find the gallons of gas used. This represents a reverse calculation from the one provided above.
