Can you calculate this gas mileage?

Question

I am driving across country and the mileage will be 1630.97 miles. How do I calculate how much gas I will be using so I can estimate $ spent. Math majors please apply.

Answer 1

whats the equation?

Answer 2

First, let your car get to almost zero gas. Take your odometer reading. Fill up your tank to full. Note how much you have to spend on a full tank of gas and how much gallons you just bought. You will need this info later.

Drive in a regular manner. When the time comes that your car has almost zero gas again, take the odometer reading again. Subtract your previous reading from your current reading. This will give you the approximate no. of miles a full tank of gas could give you. Call this X.

Divide the total mileage(you mean distance?) of 1630.97 by X. This should give you the number of full tank of gas you'll be needing. Multiply that by the amount you spent on a full tank(the note you took earlier). This is the approximate total amount you will spend on gas. Add $1000 as a backup, just in case you get lost, need more AC as usual or carrying too much luggage that it makes your car use more gas than usual or for any emergency.

Note: you also don't need to get the gas to almost zero. Just make sure that when you make the readings, the gas are at about the same level.

Added: when you talk about mileage, I'm assuming you're referring to  the distance or miles to get from a-b. Mileage is the reading you get from its odometer(what's the mileage on your car?).It also means the miles(or distance)a vehicle can travel on a specified quantity of fuel .

Answer 3

If you know how many miles your car gets to the gallon, then you divide the total miles by your mpg, then multiply by the price of gas.  If your car got 23 miles per gallon,  then you have 1630.97 / 23 = 70.911 gallons of gas.  Then you multiply that by the price of a gallon of gas.  70.911 * 2.95 = 209.19.  Make sure you have more than you need, because you never know when you will get stuck on traffic or in road construction.  I always bring about 20% more than I need.

Answer 4

You need to figure out your gas mileage in country vs. in town, and how much of the commute will be which situation.  You should know that your miles per gallon varies with the speed you doing, and how much stop and go traffic, and the condition of your car.

For example, if you get a car tune up, oil change, etc. shortly before your trip, you will use less gasoline.

If you refrain from a lot of speeding on your journey, you will use less gasoline.
