  • 22.71 Gallons per 100km

    50*100kms in 5000km

    Total Fuel = 22.71×50=1135.5

    To 3 Sig Figures = 1140

    I think thats right

  • 6.0 liters per 100 km

    6.0 liters per 62.14 miles (if 1 km = 0.6214 mile then 100km = 62.14 mile by multiplying both by 100)

    (Divide both by 62.14) 0.09655 liters per 1 mile

    0.09655 divided by 3.785 (to convert from liters to gallons)

    0.0255 gallons per mile.
