How much does it cost to travel from Portsmouth to Northampton by car?

The journey, fueled by petrol, comes to £21.9. In this calculation, we've assumed a petrol price of 143 pence per liter and the car's petrol consumption at 37.5 miles per gallon.

For those considering carpooling, with two passengers, the cost per person is £10.95 (£21.9/2). With three passengers, the cost reduces to £7.3 per person (£21.9/3). And for four passengers, it further decreases to £5.48 per person (£21.9/4).

To break it down further, here's how we arrive at the result:

The fuel required is determined by dividing the distance by the car's fuel consumption. For a journey of 126.08 miles, this calculation involves multiplying 126.08 miles by 4.54609 (liters per gallon) and dividing by the car's consumption of 37.5 mpg, resulting in 15.3 liters of fuel needed.

The fuel cost is then calculated by multiplying the fuel needed by the price per liter. For 15.3 liters of fuel at 143 pence per liter, the total comes to £21.9.

In conclusion, the fuel cost from Portsmouth to Northampton amounts to £21.9.

 

One thing that can affect car fuel consumption is tire air pressure for the following reasons:

  1. Rolling Resistance: Properly inflated tires have less rolling resistance, meaning they require less energy to keep the vehicle moving. This reduces the workload on the engine and improves fuel efficiency. On the other hand, under-inflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel.

  2. Optimal Performance: Tires that are inflated to the manufacturer's recommended pressure level ensure optimal performance and fuel efficiency. Deviating from this recommended pressure level, either by under-inflating or over-inflating the tires, can lead to decreased fuel efficiency.

  3. Tire Wear: Improper tire inflation can cause uneven tire wear, which can further increase rolling resistance and fuel consumption. Regularly checking and maintaining proper tire pressure can help prevent premature tire wear and maintain fuel efficiency.

  4. Handling and Stability: Properly inflated tires also contribute to better handling and stability, especially during cornering and braking. This can lead to smoother driving, which in turn can help improve fuel efficiency by reducing the need for sudden acceleration or braking maneuvers.

  5. Environmental Impact: Maintaining proper tire pressure is not only beneficial for fuel efficiency but also reduces tire wear and extends tire life. This helps reduce the environmental impact associated with tire disposal and manufacturing, contributing to overall sustainability.

Overall, maintaining proper tire air pressure is essential for optimal fuel efficiency, vehicle performance, and safety. Regularly checking and adjusting tire pressure according to the manufacturer's recommendations can help drivers save fuel and reduce their environmental footprint.
