You have to solve for gallon per mile, then apply to miles traveled. If the car uses 20 gallons of gas to go 350 miles, then how much gas will it take to go 1 mile? fortunately per is the same thing as a division sign, so divide 20 by 350 and you will get a small weird number (.057142857). this is how many gallons of gas (or rather what fraction of a gallon of gas) it will take a car to go 1 miles. then multiply by 850 to get gallons it would take to do that 850 times.
If you set this up as an algebra problem it will look like this, then you can cross multiply and solve for X.
350 miles / 20 gallons = 850 miles/ X gallons. if you multiply both sides by x, you get 350 miles X/ 20 gallons = 850 miles. Then multiply both sides by twenty which gives you 350 X = 17,000. Then divide both sides by 350 and your left with X = 48.57 gallons of gas.

16.25 miles/gallon 100 gallons x 16.25 miles = 1625 miles
12 miles / 3 gallons = 4 miles per gallon So for 1 gallon, the car can travel 4 miles.
At 20 miles per gallon, it would take 9 gallons to travel 180 miles.
Setup the equation like this:8 gallons / 76 miles = ? gallons / 500 milesYou can then multiply both sides by 500 to get:8 * 500 / 76 = ? gallons = 52.63 gallonsIn fact, you can type the original equation into google.com, and it will do the calculation for you.
How many gallons the van needs to travel 550 miles? A van travels 220 miles on 10 gallons of gas.
