1 km is a measure of distance, not speed. On the other hand, miles per hour is a measure of speed not distance. So there is a basic fault in the question.
1 km = 0.621 miles
and 1 km PER HOUR = 0.621 miles per hour
1 kilometer = 0.621371192 miles
127.38109440865345 Miles per Hour
11.7 feet per second. ------------------------------ Of course, there are many other possible answers to this question, for instance, (8miles/hour)(1km/0.62mi) = (8/0.62)km/h = 12.9km/h. Notice that 1km = 0.62mi, and (1km/0.62mi) = 1. This approach is the key to all unit conversions, since when you multiply by 1, the quantity (speed) doesn't change.
The man is approximately running at 9.3205679 mph.
657.0950374 miles per hour
That is the speed. It's like miles per hour. 1km per hour means 1 kilometer or 1000 meters per hour
60 miles = 96.56064 kilometres So at 1 km per hour, it would take 96.56064 hours.
1 kilometer = 0.621371192 miles
1km per hour is 1/3 of 3km per hour, so the answer is 1/3 of an hour or 20 minutes.
800,000 km per hour is approximately 497,097 miles per hour.
