if a man can run 100m in 13 sec.
whats is his speed in km/h or miles/h | answer
speed=100/13=7.7 m/sec=7.7*3.6 km/h=27.7 km/h
Usain Bolt's speed =37.5 km/h
http://en.wikipedia.org/wiki/List_of_world_records_in_athletics | You could simplify it a bit by saying that the speed is 100m in 10sec,
I know that would be a lot of difference in a race, but anyway.
That would be 10m per second.
60 sec in a minute, so 600m per minute
60 minute in an hour, 36,000m per hour
Convert to km:
approximately 36km per hour (~22.37miles per hour)
If you want exact as in 100m in 13sec
Then he traveled 100/13 m in 1 sec, that is | sorry, accidentally hit enter
Saddam gave you the rest.
37.5km/h is about 23.3 miles per hour |
