تكلفة رحلة الطريق

معادلة

Fuel used (gal)   = Distance (mi) ÷ MPG
Total fuel cost   = Fuel used × Price per gallon
Cost per person   = Total cost ÷ Passengers
Cost per mile     = Total cost ÷ Distance

مثال

رحلة 300 ميل ، 30MPG ، 3.50 دولار للغالون ، 2 ركاب:

Fuel used = 300 / 30 = 10 gallons
Total cost = 10 × $3.50 = $35.00
Cost per person = $35.00 / 2 = $17.50
Cost per mile = $35.00 / 300 ≈ $0.117
