Miles and metres do not go together very well.
Miles and decimal miles however, work splendidly, as long as thirds and two thirds are avoided (0.333333 and 0.66666) because of course they are not exact when expressed as a decimal.
That means that miles can be divided into exact yards and expressed as exact decimal miles.
I might be missing something here, but working out what the running mile costs from the above tariff looks less than straightforward to me.
Personally as a passenger what I need from a tariff sheet is simply a table of representative fares for various distances and various traffic conditions.
For instance a table might have journey distances from 1 mile to 15 miles laid out on the top row, with three row names underneath, such as Light, Medium and Heavy Traffic.
Thats now a table showing forty five representative fares for tariff one.
Two similar tables for the other tariffs underneath with a brief note on waiting time, the soiling charge and any extras.
And thats the passenger and driver friendly tariff sheet sorted.
