The gas tank of your parents car holds 12.9 gallons of gas. Because their car averages 27.8 miles per gallon, how many times will they have to fillup the gas tank to drive to cincinnati and back? From Detroit, Michigan to Cincinnati, Ohio = 264.1 miles.
264.1/27.8 equals the number of gallons used.
divide that by 12.9
thanks!
To find out how many times your parents will have to fill up the gas tank, we need to determine the total distance they will be driving and then divide it by their car's average mileage per gallon.
First, calculate the round trip distance from Detroit, Michigan to Cincinnati, Ohio. Since they will be driving to Cincinnati and then back home, multiply the one-way distance (264.1 miles) by 2:
Round trip distance = 264.1 miles * 2 = 528.2 miles
Next, divide the round trip distance by the car's average mileage per gallon:
Number of fill-ups = Round trip distance / Average mileage per gallon
Number of fill-ups = 528.2 miles / 27.8 miles per gallon
Now, let's calculate the number of fill-ups using the above equation:
Number of fill-ups ≈ 18.99 fill-ups
Since we can't have a fraction of a fill-up, we round up the number to the nearest whole number. Therefore, your parents will have to fill up the gas tank approximately 19 times to drive to Cincinnati and back.
