to drive 642 miles at 25 mpg = 642/25 = 25.7 gallons
Divide the number of miles travelled by the number of gallons of gasoline used.

Divide 360 by 12, then multiply by 4
The next time you fill up record the mileage. The next time after that record the mileage and the gallons it took to fill up. Then divide the mileage by the gallons and the answer will be the miles per gallon of that vehicle.
There are too many variables to really give a solid answer. * What route are you taking? * What gas mileage does your car get? * How will the gas mileage vary based on temperatures, altitude and various speeds? * What is the price of gasoline at all the different gas stations? You can get a general idea by taking the mileage, divide it by the MPG your vehicle gets and multiplying it by the average cost of gasoline. The distance is about 1740 miles. If you get 20 mpg it will take 87 gallons of gas. If it is $4 a gallon that would be $348 worth of gasoline.
1.35 per gallon. Divide $21.60 by 16 gallons to get the price per gallon.
Fill up your tank with gas and mark down your mileage, drive until you need gas again and fill up. Mark down your mileage along with how many gallons you put in. Subtract the latest mileage from the first mileage you wrote down and then divide the gallons put in.
It varies from car to car and driver to driver. The next time you fill up, record the mileage. The next time you fill up again, record the mileage and the gallons it took to fill it up. Subtract the the first mileage reading from the second reading and you have the total miles driven. Now take the number of gallons used and divide them into the total miles driven between fill ups and you will have the miles per gallon (mpg) the vehicle gets with you driving.
Just write down the mileage when you fill up your car and drive until you need gas again. Note the mileage at that fill-up, subtract from the previous mileage and divide by the gallons of gas to fill up.
A basic simple way of calculating mileage is taking a look at the number of miles you have driven your car and divide it with the number of gallons your car consumed to travel that long.
Divide mileage (750) by miles per gallon (18) to determine how many gallons will be needed and then multiply by the cost of gas (4.12) to determine the cost for the trip: 750 ÷ 18 = 41.67 x 4.12 = $171.68
Write down your mileage when you fill up your tank and how many gallons of gas. On the next fillup write that mileage down and subtract it from the first number. Divide that number from the number of gallons you put in. This will give you your MPG.
