What you first need to do is figure out how many miles you can travel on one gallon of gas. And then multiply this by how far you're traveling.
figure out how many miles your car gets to the gallon, let's say it gets 20... then find out how many gallons your tank holds, let's say it's 15... divide 989 miles to travel by 20 miles to the gallon = 50 gallons 50 gallons divided by 15 = 3.3 tanks of gas..... or the easier way if you're worried about how much it will cost,,,, do 50 gallons times how much you pay for gas......
