It depends on the miles per gallon your vehicle gets. If it get 20 miles per gallon then divide 700 by 20 and you get 35 gallons.
515 miles divided by 22mpg is 23.4 gallons used. 23.4 gallons times 2.50 a gallon is 58.50.
(283)/(the number of miles per gallon that your car gets)
To get the number of gallons, simply divide the distance by the miles per gallon. 2000 miles / 16 mpg = 125 gallons
1057/31 = 34.1 gallons.
You will need 1.107 gallons of fuel.
1800 miles @ 40 miles per gallon = 1800/40 = 45 gallons 45 gallons @ 4.00 a gallon = 45*4.00 = 180.00
Depends on how far you want to drive!
400 miles at 25 miles per gallon = 400/25 gallons = 16 gallons. 16 gallons at 4 per gallon = 16*4 = 64 units of currency.
That depends on the car you drive. Say it gets 30 miles per gallon. The it takes 3 gallons. On the other hand, if you get 15 miles per gallon, it takes 6 gallons. So it all depends.
25/7 = 3.571 gallons (rounded)
The idea is to 1) Divide the miles by the miles-per-gallon, to get the number of gallons, and then 2) Multiply the number of gallons by the price per gallon.
