hi, what speed (km/h) would i need to run at to complete this challange?
could you also explain your findings please?
mods - feel free to move this to the maths section

1 mile in 1 min = 60 m/h = 96.56 km/h :eek:

Good luck

I concur.

96.56 kmh

Current world record is 3:43.13 which is just under 26kmh

24.14kph (divide by 4)

What speed did Mr Bolt get to on one of his 200m jogs in miles per hour?

bo-sco · 19-02-2011 9:17pm

Well roughly speaking, a 20 second 200 would be 600m a minute, which is 36km/h. He is running quicker than that.

Read somewhere that Bolt's top speed was near 48kph, close to 30mph

200m in 19.19 seconds
*5
=1k in 95.95s
*1.609344 (1 mile = 1.609344km)
=1 mile in 154.416557s
1mile/154.416557s
=0.00647598949 miles in 1 second
*3600 (the number of seconds in an hour)
=> 0.00647598949*3600
=23.3135622 miles per hour
=37.519541 km per hour

F - well done on calculating Usain's average speed, please read robinph's question again and answer the question.

Speed=distance/time <pedantic>

We're both right

I don't know.:o

Lots of different speeds, Mr. Smartypants. So, to answer robinph's question, "Usain Bolt got to a speed of 10 miles per hour on one of his 200m jogs in miles per hour". (Other answers are also acceptable)

BeepBeep67 · 20-02-2011 12:05am

Well robinph asks what speed did Mr Bolt get to, which is a specific question but difficult to answer. A bit of googling found this:
http://videosportsanalysis.blogspot.com/2009/08/analyzing-usain-bolts-1919-second-200m.html
Bolt's maximum velocity during the 200 meter race occurs somewhere between the 50 and 100 meter mark. His average velocity over this 50m part of the race is 11.57 m/s (25.88 mph). In comparison his 100m maximum velocity was 12.27 m/s (27.45 mph).

robinph · 20-02-2011 2:21am

Hmm, I thought the 200m was faster top speed than the 100m. Good that there are other people out there to decode Google for me.
