First off, we need to consider the price of petrol. In this calculation, it's set at 144 pence per liter. Then, we need to know how thirsty your car is. The fuel consumption rate for this ride is 37.5 miles per gallon.

Now, if you're carpooling, the cost gets divvied up. For two people sharing the ride, it's gonna be 12.2 quid each (£24.4 divided by 2). If you've got three folks in the car, the cost per person comes down to about 8.13 quid (£24.4 divided by 3). And if it's a full house with four passengers, each person chips in 6.1 quid (£24.4 divided by 4).

Once we know how much fuel we need, we can calculate the total cost. Multiply the amount of fuel (16.9 liters) by the price per liter (144 pence), and you get 24.4 quid. So, there you have it, the fuel cost for your journey from Portsmouth to Cwmbran: 24.4 pounds.
