For 2 passengers in carpooling, the cost of this trip is 13.6 £ (27.2/2) per passenger.
For 3 passengers in the car, the cost of this trip is 9.07 £ (27.2/3) per passenger.
For 4 passengers in the car, the cost of this trip are 6.8 £ (27.2/4) per passenger.


Fuel cost = (155.87 mi / 37.5 mpg) x 144 pence per liter = 27.2 £

In more detail, the result is obtained:

Fuel needed = Distance / Car fuel consumption = miles * 4.54609 / carConsumtion = 155.87 mi * 4.54609 / 37.5 mpg = 18.9 liters

Fuel needed = 18.9 lt

Fuel cost = Fuel needed x Price per liter = 18.9 liters x 144 pence per liter = 27.2 £

Fuel cost from Watford to Penarth = 27.2 £

When comparing diesel fuel and petrol (gasoline) fuel in terms of octane rating, there's a significant distinction:

  1. Petrol:

    • Petrol typically has an octane rating ranging from 87 to 95 in most markets.

    • Octane rating measures the fuel's resistance to premature detonation or knocking in spark-ignition engines.

    • Higher octane ratings are crucial for high-performance petrol engines with higher compression ratios or turbocharging, as they help prevent engine knocking and allow for more efficient combustion.

  2. Diesel Fuel:

    • Diesel fuel doesn't have an octane rating in the same sense as petrol because it's not used in spark-ignition engines.

    • Diesel engines rely on compression ignition rather than spark ignition, meaning the fuel-air mixture ignites spontaneously due to high pressure and temperature.

    • Therefore, diesel fuel is designed to ignite under the high compression conditions found in diesel engines, and its properties are optimized for this type of combustion rather than for octane rating.

In essence, while petrol relies on octane rating to ensure proper combustion in spark-ignition engines, diesel fuel is formulated to ignite under the high-pressure conditions of compression ignition in diesel engines, rendering octane rating irrelevant for diesel fuel.
