Driving directions from Cardiff to Milton Keynes
How much is the expense of driving from Cardiff to Milton Keynes?
The expense of driving from Cardiff to Milton Keynes, using petrol as the fuel source, amounts to £24.6. This calculation derives from considering the petrol price as 143 pence per liter and the car's fuel efficiency at 37.5 miles per gallon. When carpooling with two passengers, the cost of the trip per passenger is halved to £12.3 (£24.6 divided by 2). With three passengers, the expense drops to approximately £8.2 per passenger (£24.6 divided by 3), and with four passengers, it's reduced further to £6.15 per passenger (£24.6 divided by 4).
To delve into the details of the calculations, the fuel cost computation is reliant on the distance traveled and the car's fuel consumption rate. For the journey from Cardiff to Milton Keynes, approximately 17.2 liters of fuel would be required. This amount is determined by dividing the distance of 142.15 miles by the car's fuel consumption rate of 37.5 miles per gallon, and then converting from gallons to liters using the conversion factor of 4.54609 liters per gallon.
Multiplying the fuel needed by the petrol price per liter results in the total fuel cost of £24.6 for the trip. This breakdown illustrates the impact of various factors, such as fuel price and consumption rate, on the overall cost of the journey, providing insights for individuals planning similar trips and requiring budget estimates.
Road conditions affect fuel usage for the following reasons:
Surface Roughness: Potholes, fissures, and uneven pavement increase rolling resistance. This makes the tires work harder to maintain speed, increasing fuel consumption.
Tire-road surface friction increases with poor road conditions. Friction causes drag, which makes the engine work harder. Therefore, fuel usage might rise, especially at high speeds.
Traffic Congestion: Heavy traffic causes stops and idling in traffic queues. Constant acceleration and deceleration might increase fuel consumption compared to open roadways.
Elevation Changes: Steep inclines or falls can effect fuel usage, especially for smaller engines. Uphill climbing takes more engine power and petrololine, whereas descending downhill may require more braking and fuel to regulate.
Rain, snow, and ice can impair road traction and vehicle stability. Adjusting speed and driving behavior can affect fuel consumption.
Good pavement and smooth roads use less fuel than rough or badly maintained roads. Smooth roads reduce rolling resistance and improve vehicle efficiency.
Road conditions greatly affect fuel use, so drivers' fuel economy may vary.
