MrIxolite Jul 17, 2003	Surely if its just struck two o clock it will take an hour for it to strike 3 o clock? :p
fishmed Aug 28, 2003	That was funny. I agree. It would take the hour for the clock to strike 3. Good one though.
boodler Nov 25, 2005	Two people either willfully or unconciously mis-reading the question! Quite easy if you think about it
stephiesd Dec 19, 2005	i don't get it. wouldn't the two seconds include the actual chiming?
musicmaker21113 Jan 12, 2006	I agree with all these comments, actually. My first answer was 1 hour... since you'd have to wait until it was 30. My second answer was actually three seconds, with this reasoning: 2 chimes took 2 seconds. That mean the first chime started to ring on the hour and rang for 1 second, the second chime started at 1 second past the hour and rang for 1 second. So, 1 second per ring... 3 seconds. Good idea for a teaser, just open to interpretation a bit.
Atropus Feb 12, 2006	The teaser is completely correct, if you assume that it takes NO time for the clock to chime and you are measuring the gap only... If you had an imaginary clock that could chime for zero seconds O_o.. there would be a 2 second gap between the first and second chimes (then it would take 4 seconds to chime 3 times). If it took half a second for the clock chime (sound).. that would leave a 1 second gap between chimes (then it would take 3.5seconds to chime 3 times). However.. IF the chime (sound) took 1 second, there would be NO gap at all (so it would take 3seconds to chime 3 times). (hmmm verbosity alert -_-;)
keveffect1 Mar 07, 2006	Yeah the teaser is right but I also think it's dull and stupid
coltonr1 Mar 15, 2006	noooo finaly 1 got me lol nice job
TehIgnored Mar 28, 2006	I think you just need to add a point of reference....stating where it's starting before moving to 2.... it could have started at 12....which is my assumption....then 12 to 1....1 to 2.....that's 2 seconds....1 second per interval..... In fact...the more I think about it, the more I disagree with this being solvable......you WOULD need a point of reference to obtain a logical answer....otherwise it's a trick.
perrygf Jun 21, 2006	I also took the time of the chime into account, particularly because chimes on clocks tend to resonate. (I also thought of the "hour" answer, but the question really didn't ask how long from NOW, but how long WHEN IT HAPPENS). Nice trick, though.
ava199345 Jul 19, 2006	im not gonna get into a long discussion about it. im gonna say straight up that i just didnt get it
ciotog Feb 11, 2007	According to the logic of the answer, it takes zero seconds to chime 1 o'clock. Does that seem reasonable?
Jimbo Mar 19, 2007	Well if you stand with a stopwatch at the foot of the clock and press start when you hear it strike 'ONE', when are you going to press stop? Let's put it this way if you are driving in your car and it takes 2 seconds to pass 2 power poles then it would take 4 seconds to pass 3 power poles and you can't time the interval required to pass one pole.
