I don't think "invented" is a good word in this case. If you want to describe the speed by which something is travelling you unavoidably end up with unit of distance/unit of time. Miles/hour was something that fitted vehicles very well. Yards/second would work, but measuring the distance between cities in yards gives awkward big numbers.

If you are going "one mile per hour", it takes exactly one hour to go a mile.

approximately 5.5 miles/hour ============= Solution Method: ----------------- There are 60 minutes in 1 hour. We often say there are 60 minutes per hour. We express this relationship mathematically as: 60 min/hr To convert miles/min to miles/hr, do the following: 1 mile/11 min * 60 min/1 hr = 60 / 11 = ~5.45 miles/hr (average speed) * Note: minutes cancel in the numerator & denominator). ----------------- Original answer: 60/11 = 5.45 recurring (that is, 5.45454...) miles per hour. Therefore, running a mile in 11 minutes corresponds to 5.45 recurring miles per hour.
