Calculate the fuel cost of a journey from distance, consumption and price.
Consumption quoted as litres per 100 km multiplies directly by distance once divided by 100. Splitting the total across passengers gives the per-person figure that makes driving comparable with a train or flight ticket. Fuel is the largest variable cost of a road trip, and the per-kilometre figure is what mileage reimbursement and cost-sharing conversations turn on.

Litres = distance × consumption ÷ 100; cost = litres × price per litre
