What is the financial outlay associated with traveling from Llanelli to Merthyr Tydfil by car?

The journey, powered by petrol, incurs a cost of £7.2. 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 £3.6 (£7.2/2). For a trio of passengers, the cost per person reduces to £2.4 (£7.2/3), and for a quartet of passengers, it further decreases to £1.8 (£7.2/4).

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 41.52 miles, this computation entails multiplying 41.52 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 5 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 5 liters of fuel at a rate of 143 pence per liter, the cumulative cost equals £7.2.

In summation, the total fuel expenditure for the trip from Llanelli to Merthyr Tydfil stands at £7.2.


Diesel cost from Llanelli to Merthyr Tydfil.

The trip with diesel fuel costs 4.5 £ (151p/lt, 62.7 mpg).
For 2 passengers: 2.25 £ (4.5/2) /p.
For 3 passengers: 1.5 £ (4.5/3) /p.
For 4 passengers: 1.13 £ (4.5/4) /p.


Generally, diesel engines typically consume less fuel than petrol engines when all other factors are held constant. This is mainly because diesel fuel has a higher energy density and diesel engines are more thermally efficient. Diesel contains more energy per liter than petrol, and diesel engines are usually better at converting this energy into mechanical power. Moreover, diesel engines operate at higher compression ratios, enhancing their thermal efficiency and enabling them to extract more energy from each unit of fuel. Consequently, diesel vehicles often deliver superior fuel economy and can cover longer distances per gallon or liter of fuel compared to petrol vehicles of similar specifications.
