varies
Kilo means thousand. five kilometers = five thousand meters
If you run 1 mile in 15 minutes it will take you 46 minutes 36 seconds run 5km
70 Kilmeters
6 kilometers is 3.73 miles, so take the amount of time it takes you (or your subject[s]) for a mile, and multiply that time by 3.73.
if it takes you 18 minutes to run 3.2 kilometres, then it would take an estimate of about 6 minutes for 1 kilometre because you run slightly faster in the beginning!
takes me 30 minutes to run 6.25 kilometers
It would take Wilma 8 hours to run 40 miles at 5mph.
43000 Hours
forty five minutes
About 16.1 km
It all depend on the person running the 20k. Are they a pro, fat, skinny, and how often they run.
