How do i work out the mpg for my new car. It cost me £35 for 400 miles of travel. How do u work out the mpg?

Answer 1

hi, if you divide the value of the amount of petrol you have put in by the cost per gallon - that will give you how many gallons you have bought.
you then divide the 400 miles by number of gallons bought - to give your mpg!

Answer 2

well, 35 divided by 400 is 8.75p, so thats how much one mile must cost. to find out the MPG you need to know how many gallons you actually put in the car to start with, then divide that by 400. so if for instance you put 20 gallons in, 400 divided by 20 is 20, meaning that you got 20 miles per gallon. Of course I'm sure thats nowhere near your actual usage, I just used that as a simple example. You could also (if your car has one) reset the trip counter after you fill up, and see what the total mileage on it has reached when you next fill up.

Answer 3

you need the gallons of fuel you used not the money. If you use the money it would be money per gallon. Fill your tank completely full, reset your trip, and drive it as you normally would. The next time you fill up your tank take note of how many gallons you need to put in your car to fill it. Then take the number of miles you drove and divide it by the gallons you used. Miles divided by gallons = miles/gallon = miles per gallon = mpg

Answer 4

After you fill the tank make sure to write down how much gas you put in. The next time you get gas note that too along with the mileage between times.

Now here comes the calculation:

MPG = total mileage between fillups divided by (First time minus last time)

That will give you the accurate mpg.

Answer 5

Run the tank down til it's pretty well empty then fill it up. Write down how many gallons you put in. Run the tank down to empty again, this time write how many miles you drove. Miles divided by gallons = mpg

Answer 6

400 miles divide by gallons used to get mpg.

for example:

400 (miles)/12(gallons)=33.4 mpg

if you're buying in litres, you'll have to convert to gallons.

multiply litres by 0.2641720 to get u.s. gallons liquid.
