Depending on driving conditions - about 2.5 gallons.
It depends on the cost of said petrol and the efficiency of the vehicle in "miles per unit of petrol". You didn't supply enough information.
From Cardiff to Glasgow is some 400 miles and would cost about £75 in petrol.
In an average car, you would need about six liters of petrol to drive 38 miles. This is equal to about 1.5 US gallons.
It would cost (2.4) times (the cost of one gallon petrol). Also, add cost of tolls, food, etc.
None, if you cycle! If you drive, it depends on the fuel efficiency of your vehicle and your driving style.
At an average 50 miles an hour, it would take 40 hours.
That would depend on the average speed. If the average is 50 mph, they drove 650 miles.
500 miles is always 500 miles unless it's nautiical miles. I'm not sure if 500 miles in petrol would be classed as nautical miles.
I had this problem before and it was the petrol sensor or a sensor by the filter. Or it could be your revers need turning down
To calculate the time it would take to travel 200 miles, divide the distance by the average speed. Assuming an average speed of 40 MPH (miles per hour). 200 ÷ 40 = 5 hours At 33 MPH it would be about 6 hours.
112.86 hrs.
