How Can I: Calculate Gasoline Metrics?

OMG I am so brain dead right now. I cannot come up with formulas for how to get to goal here.

KNOWN:
Liters per tank: 65 (fixed)
Kilometers per tank: 450 (variable)
Gas Cost: $1.159/L (variable)

GOALS:
I want to enter the variables for the cost and kms per tank, then output:
Distance per KM
Cost per KM
Distance per L

I realize that everyone here is going to be mocking me for this ridiculous question. I just can't think the correct thoughts. My brain is paralyzed right now.

Thanks for the help everyone.

Distance per KM

Did you mean litres per km?

I want that as well, thank you.

Oh, and Distance per KM = Kilometers per tank / Kilometers per tank = 1

Thanks for this, that's great.

As for fuel economy (liters per 100kms)... Can you confirm the formula here please? I am not getting values that I believe, which is because I am a mathematics idiot.

You already have L per KM, so just multiply by 100, ie. 14.44 L/100KM, and $16.70/100KM

At least Four
