At an average speed of 55 MPH, it would take 2 hrs. and 15 mins. to travel 200km (124.27 miles).

There are 397.677563 miles in 640 kilometers. 640 kilometers x 1 mile/1.609344 kilometers = 397.677563 miles 1 mile = 1.609344 kilometers

Usain Bolt run 100 m (with a running start) with a speed of 41 km/h.

-10 Kilometers-10, 000 Meters-1,000,000 Centimeters-6.2 MilesIf you meant 'How long would it take' then i really depends on who is running it. There is no set time on how long a run takes. If you want to find out how long it would take you then find out your comfortable speed for a long run (measure time between two points then calculate Speed = Distance/Time) then multiply it up for 10 kilometers. Say it takes you 1 minute to run 1 kilometer (60kph, unlikely i know) then it would take you 10 minutes to run 10 kilometers. Assuming that you maintained a constant or average of the quoted speed.

A mile is a unit of distance. An hour is a unit of time. Without some unit of speed to compare, the two units are incompatible.

Kilometers/Miles per hour

130 kilometers is not a speed, but a distance. A speed would be expressed, for example, in kilometers per hour, kilometers per minute, or kilometers per second. In case you are more accustomed to miles, dividing the kilometers by 1.6 gives you the approximate equivalent in miles.

55 km = 34.18 miles

The crusing speed of the concord jet is Mach 2, or 1,336 mph (2,150 kph).

You can't feel speed. You can only feel changes in speed. That's how you're able to read a book on a moving train, and have a comfortable nap on a jetliner flying 7 miles above the ground at 400 mph.
