How to figure out miles per gallon that I am getting in my car????

[patricia92243]

I don't know the formula to use. I think you subtract something from something then divide something else by something else, but I don't know what.

My numbers are: 43,647 miles on my car and 6.825 gallons of gas. Then: 43,840 and 6.729.

Help!

Thanks

1. Well, you went 193 miles on 6.729 gallons of gas.

Basically, you fill the tank and note the mileage. Then, next time you fill the tank note the mileage AND note the number of gallons purchased. Then, subtract the mileages and divide the result by the number of gallons purchased.

2. My math:

43,840 - 43,647 = 193 miles
6.729 gallons used (assuming you filled the tank both times.

193 / 6.729 = 28.68 mpg.

Many cars have a trip odometer, that you can reset to 0 by pushing a button. I usually reset mine when I fill the tank, so I know at a glance how many miles I've driven on that tankful.
