Calculate the fuel economy of your family or personal car in terms of gallons per mile and the total cost for one fill-up git hu
iren [92.7K]

Answer:

0.028 Gallons/mile

Step-by-step explanation:

1 Gallon = 3.78541 Litres

1 Mile    = 1.60934 Km

Total Fuel Expenditure (Dec 2019) = PKR 7,000

Fuel cost / Litre = 114Litre/Km

Total Fuel consumption = (7000/114)

                                      = 61.40 Litres or 16.22 Gallons

Total Distance Travelled in Dec 2019 = 921 Km or 572.28 miles

Fuel Economy = 16.22/572.28

                       = 0.028 Gallons/mile

One time tank fill up cost = PKR 1,500
