Damocles said:Duphrates said:You have three one-hour fuses (the kind on TNT). Unfortunately, they don't necessarily burn at a uniform rate; all you know is that each one takes exactly one hour to burn completely. You need to make a fuse which is 45 minutes long.
How do you do this?
I'm not sure I understand this, this is what I've got from this:
I have three fuses of different length that all take an hour to the end.
I need to make a fuse that lasts for 45 minutes.
?
EDIT : I'm so fucking dumb.
Light Fuse 1 at both ends, Light fuse 2 at one end.
When fuse 1 has died, you know 30 minutes have gone. Light the fuse two at both ends now and light 3. When fuse 2 goes out, it takes 15 minutes. Put out Fuse 3, which you now is a 45 minute fuse.
I made that much harder than it had to be :P
BINGO!
