What's the expense of traveling from Cardiff to Weymouth and Portland by car?

If you're using petrol, you're looking at an expense of 22.2 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 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 11.1 quid each (£22.2 divided by 2). If you've got three folks in the car, the cost per person comes down to about 7.4 quid (£22.2 divided by 3). And if it's a full house with four passengers, each person chips in 5.55 quid (£22.2 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 Weymouth and Portland is about 127.35 miles. So, to cover that distance, your car's gonna need approximately 15.4 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 (15.4 liters) by the price per liter (144 pence), and you get 22.2 quid. So, there you have it, the fuel cost for your journey from Cardiff to Weymouth and Portland: 22.2 pounds.
 

Diesel cost from Cardiff to Weymouth and Portland.

The trip with diesel fuel costs 15.4 £ (167p/lt, 62.7 mpg).
For 2 passengers: 7.7 £ (15.4/2) /p.
For 3 passengers: 5.13 £ (15.4/3) /p.
For 4 passengers: 3.85 £ (15.4/4) /p.

Diesel fuel and gasoline (gasoline) fuel in terms of how well they use fuel: 

Diesel Fuel: In general, diesel engines use less gas than petrol engines. This is mostly because diesel fuel has a higher energy density and diesel engines are better at using heat. Compared to gasoline, diesel fuel has more energy per litre or gallon. This means that diesel engines can get more energy from each unit of fuel. Diesel engines also have higher compression ratios, which makes them even more thermally efficient. Because of this, diesel cars usually get better gas mileage and can go farther on a gallon or litre of gas than gasoline cars of the same size and speed. 
Petrol (petrol): Diesel engines use less fuel than petrol engines in general. Even though gas is still a good fuel for internal combustion engines, diesel fuel usually has a higher energy density. This suggests that gas engines might need more fuel to work as well as diesel engines. The difference between petrol and diesel cars has become smaller, though, thanks to improvements in petrol engine technology like turbocharging and direct injection. 
Overall, both diesel and gasoline engines can be used to get good gas mileage, but diesel engines tend to be better because they store energy more efficiently and cool down faster. But how people drive, how the car is built, and other things can also affect how much fuel a diesel or gas car uses.
