Re: MrRubix's Riddle Thread
I didn't say there weren't. You can't tell when it's at an 180 degree angle. you can't tell the difference between 12:31 and 6:01, 12:32 and 6:02, 12:33 and 6:03, etc.
Edit: yes you can. I suck at riddles. Leave me alone =(. This is a problem of hour to minute ratios and I'm bad at ratios. so bye.Last edited by rushyrulz; 08-4-2008, 10:36 AM.

12:00
1:05
2:10
3:15
4:20
5:25
6:30
7:35
8:40
9:45
10:50
11:55
12:00
All of these times are when the minute hand AND the hour hand are in the exact same position.
So, it's 13 if you count the last 12:00 and 12 if you don't.Comment

Re: MrRubix's Riddle Thread
These are the times he CAN tell us, I already did the same thing.
He wants to know what times he can't tell us.sigpicComment

Re: MrRubix's Riddle Thread
Might be better if you try to explain, mathematically, when you would not be able to tell what time it was. And then use that framework to derive how many such times exist.Comment

Re: MrRubix's Riddle Thread
Oops...I read over the problem too quickly and assumed it was the more traditional coincidental problem (to which the answer has already been given). Yours is slightly more complex than it lends its appearance to. I'll get the solution after lunch. 8)Comment

Re: MrRubix's Riddle Thread
ohhhh i missed that the first timeIn this thread, we will dedicate discussion to various riddles/puzzles/problems.
Here's one to get you started.
Imagine that the hour and minute hands of a clock are the same length. Imagine, also, that I am able to read the hands with 100% certainty (meaning I can tell EXACTLY how far the hour/minute hands have moved).
How many times exist over a 12 hour period where, if I were to look at the clock, I'd be unable to tell you what time it was?Comment

Re: MrRubix's Riddle Thread
You will always know the time because the minute hand goes faster then the hour hand. If you are watching it for a 12 hour span of time, then you will know the time easily.
Unless it is unplugged/broken, then you won't be able to tell the time, lol.PM me if you want to rent my custom title. :3

Re: MrRubix's Riddle Thread
Some really basic help: When the minute hand goes 360 degrees, the hour hand goes 30 degrees (360/12).Comment

I thought using Matrices would help, but all it did was make me more confused...I have a sig.Comment
