For 2 passengers in carpooling, the cost of this trip is 21.15 £ (42.3/2) per passenger.
For 3 passengers in the car, the cost of this trip is 14.1 £ (42.3/3) per passenger.
For 4 passengers in the car, the cost of this trip are 10.58 £ (42.3/4) per passenger.


Fuel cost = (244.1 mi / 37.5 mpg) x 143 pence per liter = 42.3 £

In more detail, the result is obtained:

Fuel needed = Distance / Car fuel consumption = miles * 4.54609 / carConsumtion = 244.1 mi * 4.54609 / 37.5 mpg = 29.6 liters

Fuel needed = 29.6 lt

Fuel cost = Fuel needed x Price per liter = 29.6 liters x 143 pence per liter = 42.3 £

Fuel cost from St Helens to Portsmouth = 42.3 £

 

One thing that can affect car fuel consumption is the use of air conditioning (AC) for the following reasons:

  1. Engine Load: When the AC is turned on, the compressor in the car's engine needs to work harder to cool and circulate the air. This extra workload can increase the engine's fuel consumption, especially during city driving or when the car is idling.

  2. Drag Effect: Running the AC can also increase aerodynamic drag, particularly at higher speeds. This means the engine needs to work harder to maintain speed, resulting in higher fuel consumption.

  3. Accessory Load: In addition to the AC compressor, other electrical components such as the blower fan and condenser fan also draw power from the engine when the AC is running. This increases the overall electrical load on the engine, leading to higher fuel consumption.

  4. Driving Conditions: The impact of AC on fuel consumption can vary depending on driving conditions. For example, using the AC while driving at lower speeds or in stop-and-go traffic may have a more significant effect on fuel consumption compared to highway driving.

  5. Efficiency Settings: Some cars come equipped with features like "Eco" mode or variable AC compressor speeds, which can help reduce the impact of AC on fuel consumption. Using these features can help optimize fuel efficiency while still keeping the cabin cool.

Overall, while using the AC can increase fuel consumption to some extent, it's often a necessary trade-off for comfort, especially during hot weather. However, minimizing AC usage when possible, such as using the car's ventilation system or rolling down windows at lower speeds, can help mitigate its impact on fuel consumption.
