How much gas would it cost for a 1600 mile trip?

Answer 1

If you drive, the cost will depend on the cost of gas (diesel or petrol), your vehicle, your drving style, the amount of extra weight in your car, road conditions (particularly traffic), whether or not you have your air-con/heater on.

Depends on the MPG of the vehicle you are driving which you did not list. Therefor it is impossible to provide an accurate answer. But it is easy to figure out. An example would be the car you are driving averages 30 MPH on the highway. You are going 1,600 miles. So if you divide 30 into 1,600 you will get 53.33. Therefore it will require approximately 53 1/3 gallons of fuel to drive this far.
