See the guy on the far right? That's Usain Bolt (notice the Jamaican colours). As you likely know, he was the winner of the 2012 London Olympic 100 metres sprint (in a time of 9.63 seconds).
Mr. O'Gorman had the very cool idea of asking: "where would every other competitor in the London Games 100m sprint have been after 9.63 seconds". Obviously they'd all be behind Mr. Bolt, but how far?
Enter Math!! The guy in second place (same Jamaican colours) is Yohan Blake. He finished in 9.75 seconds. So after 9.63 seconds he'd be VERY close to the finish. I calculate that he'd be at 98.8 metres (sure hope that Mr. O'Gorman got the same answer). The guy in third place is Justin Gatlin (USA). His 9.79 second finishing time converts to 98.4 metres. And so on...
Pretty awesome, eh? Mr. O'Gorman is pretty proud of this (who wouldn't be). If it intrigues / impresses / inspires you in any way I encourage you to let Mr. O'Gorman know when you see him next. I KNOW that he would really appreciate it.
