well, we need to know how big the container is first, then we can work it out. and this is one of those questions where most people are gona see the word "half" and say 5:30pm!!! which is the wrong answer

EDIT: oh yea, 5:59, i was thinkin to deeply into this

oh my god, idiot kids...you dont need to know how big the container is. the water ****ing doubles every minute. that means a minute before it was full, it was half.



well SORRY FOR NOT PAYING ATTENTION.. no need to call me an idiot...

Never. It never says there is anything in the container. If you double nothing... it's still nothing.

A little more realisticly... 59 minutes.


EDIT: Damn, I took a little to long thinking that through and got beat.

I don't get it.




Since it doubles every minute, half of wat is in it was in it the minute before. If its full it was half full at 5:59, quarter full at 5:58, one eighth full at 5:57...etc. The level of the water is 2^-(60-n) or 1/2^(60-n) where n is the minutes digit. Yeah... I took way to long thinking this through.

On the other hand if the container starts filling when it starts raining and we assume that it's full but also overflowing at 6:00 then it's actually full after about 7 minutes (5:07) and half full after 6 minutes (5:06) so for it to be full but not overflowing at 6:00 you'd have to start filling it (take the lid off, put it outside, whatever) at 5:53.

w8 if theres no water to start with then it would never get full because zero times two is still zero...

Exactly full implies that it is not overflowing though.


Quote by GiantRaven
So...how full was it when it started?


If it really is 5:59, then it would have been 1/1152921504606846976 full at 5:00.
This is where my idea of it never filling came from. The riddle never says there is anything in it to start, implying it is empty. If it is empty, then you are doubling nothing every minute. If you double nothing it's still nothing so how does it fill?

1/1152921504606846976 th if I'm right.

You assumed that it wasn't; I just thought of it the other way because it didn't say it wasn't overflowing

Well if each minute before 6:00 it is half as full as it was at 6:00 then at 5:00 it was 1/ 2^60 of it's full capacity. I don't think that helps but I know I'm right.

It doesn't matter; assuming that the conditions stated in the first post are true the answer will always be the same.

If it was overflowing it wouldn't be exactly full. The surface tension of the water would actually make the water level higher than the top of the container if it was overflowing .

Then she shouldn't be teaching maths; this crap is beyond easy, it took me about 5 seconds to come up with the answer I gave and another 5 to come up with the amount it would have to start off with. Tell your head teacher so she gets fired or at least demoted.
