Speed. Kilometre measure distance, and hour is a measure of time. Distance / Time = Speed.
There is no equivalence.A kilometre is a measure of length or distance while miles per hour is a measure of speed. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.There is no equivalence.A kilometre is a measure of length or distance while miles per hour is a measure of speed.

Nothing. A centimetre is a measure of distance. A mile per hour is a measure of speed. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
None. 89 miles is a measure of distance whereas hours per kilometer is a measure of time taken to travel (inverse of speed). The two measure different things and it makes no sense to try to convert from one to the other.
The word hour is not a verb. The word hour is a noun; a singular, common, abstract noun, a word for a measure of time, a thing.
