It depends what kind of car you have. It could take anywhere from 10-less than one gallon of gas to go that far depending on the car's gas mileage.
567 miles 27x21=567
75 miles on average
20 miles a gallon
That depends on the mpg of the vehicle. A compact car convertible can go 30+miles. A 1970's era Cadillac would go less than 15 miles.
It depends on the price of gas. If gas costs $5/gallon, it would cost about $835.00 to go 5000 miles when your car get 30 miles to the gallon. If gas costs $3/gallon, it would cost about $500. cost = 5000/30 * cost-of-gas
76 gallons
175 miles on 7 gallons implies 175/7 = 25 miles per gallon. So with 15 gallons it will go 15*25 = 375 miles.
You can travel as far as your wallet (money) will let you.
25 miles per gallon, as of 2004The distance a vehicle can travel on one gallon of gas varies by the year, make, model and condition of the vehicle and whether it is traveling on a highway or not. My car gets about 26 miles to the gallon but I can go about 35 miles to the gallon on my motorcycle.
(312) divided by (the number of miles your car gets on one gallon of gas)
If your Sentra has a 13 gallon tank, probably 30-40 miles.
