How do I figure how much money in gas it would cost and how much gas it would take to go on a trip?|107027

I am going to do a wyoming trip and I can_t remember how to figure what it would cost in gas for the trip. And how much gas it would take.

1.Total the anticipated round trip mileage
2.Divide the total mileage by the miles per gallon your vehicle averages.
3. Gas cost per gallon-here will just use $3.00 per gallon

Say 1 above is 1500 miles
And 2 above is 15 miles per gallon
Then divide 1500 by 15. =100 gallon of gas you will use (in this example)
Using $3.00 a gallon, and you use 100 gallon-then your paying $300.00 for gas on your trip.

Depending on what car you drive.
Most cars are averaging about 20 cents per km. How to calculate that?
Take your full tank price divided by the maximum km your car can travel.
i.e. = $100/500km = $0.20/km
So if your trip is going to be like 600km away, if would probably cost you around $120.
