What's the expense of traveling from Cardiff to Watford by car?

The trip fueled by petrol comes to £26.4. This calculation is based on a petrol price of 143 pence per liter and the car's consumption rate of 37.5 miles per gallon.

For those interested in carpooling, the cost per passenger decreases with more occupants. With two passengers, each person's share is £13.2 (£26.4/2). For three passengers, the cost per person reduces to £8.8 (£26.4/3), and with four passengers, it further decreases to £6.6 (£26.4/4).

To delve deeper into the calculation, let's examine how we arrive at the result:

Firstly, we determine the fuel required by dividing the distance by the car's fuel consumption rate. For a journey of 152.39 miles, this calculation involves multiplying 152.39 miles by 4.54609 (liters per gallon) and dividing by the car's consumption of 37.5 mpg, resulting in 18.5 liters of fuel needed.

Next, we calculate the fuel cost by multiplying the fuel needed by the price per liter. With 18.5 liters of fuel at 143 pence per liter, the total cost comes to £26.4.

In summary, the fuel cost for the trip from Cardiff to Watford amounts to £26.4.

The trip with diesel fuel costs 16.7 £ (151p/lt, 62.7 mpg).
For 2 passengers: 8.35 £ (16.7/2) /p.
For 3 passengers: 5.57 £ (16.7/3) /p.
For 4 passengers: 4.18 £ (16.7/4) /p.

Diesel fuel and gasoline (petrol) fuel have differences:

  1. Energy Density: Diesel fuel generally has a higher energy density than petrol. This means that diesel fuel contains more energy per liter or gallon compared to petrol, resulting in diesel engines being able to generate more power and travel further distances on the same volume of fuel.

  2. Octane Rating: Petrol typically has a higher octane rating compared to diesel fuel. Octane rating indicates the fuel's resistance to knocking or pre-ignition in spark-ignition engines. Higher octane ratings are required for petrol engines with higher compression ratios or turbocharging, whereas diesel engines rely on compression ignition and do not use spark plugs.
