If you're using petrol, you're looking at an expense of 7.2 quid. Now, how do we get to that number? Let's break it down.
First off, we need to consider the price of petrol. In this calculation, it's set at 143 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 3.6 quid each (£7.2 divided by 2). If you've got three folks in the car, the cost per person comes down to about 2.4 quid (£7.2 divided by 3). And if it's a full house with four passengers, each person chips in 1.8 quid (£7.2 divided by 4).
Let's dive into the nitty-gritty of the calculations. To figure out how much fuel you need for the trip, it's all about distance and fuel efficiency. The distance between Cardiff and Port Talbot is about 41.6 miles. So, to cover that distance, your car's gonna need approximately 5 liters of petrol. We got that number by dividing the distance by the car's fuel consumption rate of 37.5 miles per gallon and then converting it to liters 'cause that's what we use here.
Once we know how much fuel we need, we can calculate the total cost. Multiply the amount of fuel (5 liters) by the price per liter (143 pence), and you get 7.2 quid. So, there you have it, the fuel cost for your journey from Cardiff to Port Talbot: 7.2 pounds.
