Distance Price Calculator

I would like to have a calculator based on distance and a rate per km such that a user can enter their distance and their rate per km to determine total cost of the trip.

This is a request for a calculator left by a user.

There is still no calculator created for this request. If you are interested in implementing such a calculator, please leave a comment.
