You need 699/30 = 23.3 gallons.
96
That depends entirely - on how many miles to the gallonthe vehicle does !
189 miles = 7 gallons 27 miles = 1 gallon 297 / 27 = 11 gallons
To travel 586 miles at 16 mpg you will need at least 36.625 gallons of gasoline.
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.
Not enough information. Basically, you need to divide the number of miles by the number of gallons.
Me? 109 miles/27 = 4.037 gallons ============== That is an average.
About 20 gallons
At 20 mpg, it will take about 6 gallons of gas.
The answer depends entirely on your gas mileage. If you're riding a moped that makes 75mpg, you'll need about 6.5 gallons. If you're driving an American muscle car that makes 10mpg, you'll need 48.5 gallons. Divide 485 by your gas mileage to find how many gallons you'll need.
Find out the total number of miles you will travel. You need to know the number of miles you get per gallon of gas for your particular car. Then divide the miles per gallon into the total miles you will travel. That will tell you how many gallons of gas you will need. It will still be fairly approximate depending on how fast you travel and the conditions of the road.
