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

The journey, powered by petrol, incurs a cost of £31.5. 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 £15.75 (£31.5/2). For a trio of passengers, the cost per person reduces to £10.5 (£31.5/3), and for a quartet of passengers, it further decreases to £7.88 (£31.5/4).

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 181.72 miles, this computation entails multiplying 181.72 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 22 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 22 liters of fuel at a rate of 143 pence per liter, the cumulative cost equals £31.5.

In summation, the total fuel expenditure for the trip from Merthyr Tydfil to Welwyn Hatfield stands at £31.5.


Diesel cost from Merthyr Tydfil to Welwyn Hatfield.

The trip with diesel fuel costs 19.9 £ (151p/lt, 62.7 mpg).
For 2 passengers: 9.95 £ (19.9/2) /p.
For 3 passengers: 6.63 £ (19.9/3) /p.
For 4 passengers: 4.98 £ (19.9/4) /p.

In general, diesel engines tend to have lower fuel consumption compared to petrol engines, all else being equal. This is primarily due to the higher energy density of diesel fuel and the higher thermal efficiency of diesel engines. Diesel fuel contains more energy per liter than petrol, and diesel engines are typically more efficient at converting that energy into mechanical work.

Additionally, diesel engines operate at higher compression ratios, which improves their thermal efficiency and allows them to extract more energy from each unit of fuel. As a result, diesel vehicles often achieve better fuel economy and can travel farther on a gallon or liter of fuel compared to petrol vehicles of similar size and performance.
