You can&#39;t have a speed that is measured only in a length unit of measure.  You have to have some number of units of length per unit of time.  So you have a distance of 80 km, but if you want to talk about speed, it has to be 80 km per hour, or minute, or second, or year or nanosecond or even Planck Time.
