How much money would it cost to drive 268 miles in a car that gets 15mpg.?

-its full tank holds 20 gallonsIf you know what the gas costs per gallon, you can figure it out easily. OK...you have all the bases covered, now do the math. Divide the MPG into the miles traveled to get the gallons used and then multiply by the fuel price.
I'll tell you how to figure it out on your own, but I won't actually tell you how much it'll cost. Divide how many miles the trip is by MPG, and that'll be how many gallons of gas you'll use. Multiply that by cost per gallon.
