What is the financial outlay associated with traveling from Plymouth to Portsmouth by car?
The journey, powered by petrol, incurs a cost of £29.4. In this computational scenario, the price of petrol is assumed to be 143 pence per liter, and the car's fuel efficiency stands at 37.5 miles per gallon.
For individuals contemplating carpooling arrangements, the expenditure per traveler diminishes as the number of passengers increases. With two passengers, the cost per person amounts to £14.7 (£29.4/2). For a trio of passengers, the cost per person reduces to £9.8 (£29.4/3), and for a quartet of passengers, it further decreases to £7.35 (£29.4/4).
To provide further elucidation on the calculation process, let us dissect how the final figure is derived:
Initially, the requisite fuel quantity is determined by dividing the distance traveled by the car's fuel consumption rate. For a journey spanning 169.66 miles, this computation entails multiplying 169.66 miles by 4.54609 (liters per gallon) and subsequently dividing by the car's fuel efficiency of 37.5 mpg, resulting in a requirement of 20.6 liters of fuel.
Subsequently, the fuel expenditure is computed by multiplying the amount of fuel required by the price per liter. Given a consumption of 20.6 liters of fuel at a rate of 143 pence per liter, the cumulative cost equals £29.4.
In summation, the total fuel expenditure for the trip from Plymouth to Portsmouth stands at £29.4.
Things that affect how much petrol costs when you drive a car are
- Prices of Fuel: One of the main things that affects fuel costs is the price of fuel itself. Fuel prices can change because of changes in global oil costs, local taxes, and market demand.
- Route Choice: The path taken while driving can change how much petrol you use. If you want to save money and petrol, choose routes with lower speed limits, fewer stops, and less traffic jams than routes through crowded cities.
- Maintenance: For the best petrol mileage, it's important to keep your car in good shape by doing things like changing the oil, rotating the tires, and tuning up the engine on a regular basis. Not doing upkeep can cause your car to use more petrol and cost you more money.
- Fuel Efficiency: A big part of how much fuel a car costs is how efficiently it uses fuel. Cars that are more fuel efficient will use less petrol per mile or kilometer, which means that you will spend less on petrol.
- Driving Habits: The way you drive, like speeding, accelerating quickly, and stopping a lot, can have a big effect on how much petrol you use. By driving more smoothly and keeping your speed steady, you can save money on petrol and use less of it.
- Vehicle Weight: Adding extra weight to your car, like extra goods or roof racks that you don't need, can make it use more petrol. Getting rid of weight that isn't needed can make fuel use more efficient and cut down on fuel costs.
