First, determine how many gallons it will take: 1200 mi ÷ 30 mi/gal = 40 gal.
Then, figure out how much it'll cost: $4.20/gal × 40 gal = $168.00
A useful idea is to keep the units with the calculation, and verify that your method makes sense by checking that you get sensible units. You can tell something is wrong, if you end up with the price being miles/$ or something silly like that.
Divide 1400 / 30 to get the number of gallons. Then multiply that by the price of gasoline per gallon.
62.79 to the nearest cent.
The answer depends on the efficiency of the vehicle in miles per gallon, as well as the price of gasoline. An average automobile goes 20 miles on a gallon of gas. Divide distance by efficiency (1000 miles divided by 20 miles per gallon results in 50 gallons.) If gas costs $3 per gallon, then the fuel used by this car to travel 1000 miles would cost $150 and you would need to fill up twice. If you drive a hybrid at 33 miles per gallon, the cost would be $90 (one tank of gas used). If you drive a truck or SUV at 10 miles per gallon, the cost would be $300 with four fill-ups.
400 divide by miles per gallon times gas price = answer
Depends on the MPG the vehicle you are driving gets and the price you pay for the fuel per gallon.
86 x the price per gallon
The answer will depend on the price of gas!
t will cost you the price of 55 gallons - whatever that price is.
You would also have to know the price of gasolene.
Find the distance. cost = (distance * price per gallon ) / miles per gallon.
You missed out two vital pieces of information... How many miles per gallon the vehicle does - and the price of a gallon of fuel !
Sounds like you are a goofball and should be walking......
240 1200/15 x 3
That depends on the price of fuel per gallon.
Depends on the price of fuel.
800 divided by 17 = 47.06 gallons As of April 23, 2011 gas price is $3.79 per gallon. 47.06 x $3.79 = $ 178.36
1800 mi / 22 mpg * $3.00/gal = $245.45 (approx; depending on exact price of gas)
