i dont know the answer for a half marathon but i read that only 1 percent of the population has run a marathon(26.2) In a 2008 New York Times article about the Half Marathon becoming the hottest new distance in running, it estimates that 650,000 people completed half marathons in the US in 2007. A Google search of the US population for 2007 gives a result of 301M total people. This would make the percentage of half-marathon finishers less than 1%. We're a pretty special group, eh? :)
407,000 runners finished marathons in the USA in 2007. With the population at around 303,500,000 that calculates to about one-tenth of a percent, or 1 per every thousand. This answer above assumes every runner runs one marathon, only. If marathoners averaged 10 marathons each in 2007, that would be one-onehundredth of a percent who run marathons, by the above figures. Even that seems high to me.
5km is equal to 3.1 miles.
because you have to be really tough to run 5 k in 18 min.
K-Pak gets 4.5 - 5 stars (out of 5) on Amazon, which means that most of the people who purchase it on Amazon love it!
If you mean: kk-5 then it can be k^2-5 But if you mean: k+k-5 then it can be 2k-5

k divided by 5
k - 5
10-k=5
k(k + 5)
0.25%
The values of k can be: 5 or -3
