A car averages 30 miles of driving for 1 gallon of gas if the car holds 12 gallons how many times will we have to fill up his gas tank during the 2520 mile trip
First, divide 2520 by 30 miles to see how many times one gallon will be used. Then, divide the answer from that (84) by 12 to see how many times you'll need to fill up the gas tank.
