What's the expense of traveling from Plymouth to Southampton by car?
If you're using petrol, you're looking at an expense of 26.1 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 13.05 quid each (£26.1 divided by 2). If you've got three folks in the car, the cost per person comes down to about 8.7 quid (£26.1 divided by 3). And if it's a full house with four passengers, each person chips in 6.53 quid (£26.1 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 Plymouth and Southampton is about 150.83 miles. So, to cover that distance, your car's gonna need approximately 18.3 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 (18.3 liters) by the price per liter (143 pence), and you get 26.1 quid. So, there you have it, the fuel cost for your journey from Plymouth to Southampton: 26.1 pounds.
Diesel cost from Plymouth to Southampton.
The trip with diesel fuel costs 16.5 £ (151p/lt, 62.7 mpg).
For 2 passengers: 8.25 £ (16.5/2) /p.
For 3 passengers: 5.5 £ (16.5/3) /p.
For 4 passengers: 4.13 £ (16.5/4) /p.
When compared to petrol engines, diesel engines typically have a lower fuel usage. This is the case even when all other factors remain the same. This is mostly attributable to the higher energy density of diesel fuel as well as the higher thermal efficiency of diesel engines. Diesel engines are often more efficient in converting the energy contained in diesel fuel into mechanical effort than gasoline engines are. Diesel fuel contains more energy per litre than gasoline fuel.
In addition, diesel engines carry out their operations at higher compression ratios, which not only enhances their thermal efficiency but also enables them to extract a greater amount of energy from each individual unit of fuel. As a consequence of this, diesel vehicles typically achieve superior fuel economy and are able to go further on a gallon or litre of fuel when compared to gasoline vehicles of comparable size and performance.
In the end, the decision between diesel and gasoline-powered vehicles is determined by a number of criteria, such as preferences about fuel economy, driving patterns, environmental concerns, as well as the availability and pricing of fuel in the local area.
