Formula & Mathematics
Trip Fuel Consumption Formula
Fuel Needed = Distance / Efficiency; Total Cost = Fuel Needed × Fuel Price
Calculates cost per kilometer/mile and divides among passengers for carpooling.
Worked Example
600 km road trip at 15 km/L with petrol at ₹100/L shared by 4 people
Distance = 600 km, Efficiency = 15 km/L, Fuel = ₹100/L, 4 passengers.
• Fuel Needed = 600 / 15 = 40 Liters
• Total Fuel Cost = 40 × ₹100 = ₹4,000
• Cost per person = ₹4,000 / 4 = ₹1,000
Total fuel cost is ₹4,000 (₹1,000 per passenger).
