What is the financial outlay associated with traveling from Harrow to Blackwood by car?

The journey, powered by petrol, incurs a cost of £25.6. 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 £12.8 (£25.6/2). For a trio of passengers, the cost per person reduces to £8.53 (£25.6/3), and for a quartet of passengers, it further decreases to £6.4 (£25.6/4).

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 147.58 miles, this computation entails multiplying 147.58 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 17.9 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 17.9 liters of fuel at a rate of 143 pence per liter, the cumulative cost equals £25.6.

In summation, the total fuel expenditure for the trip from Harrow to Blackwood stands at £25.6.
