You have a lighter and two fuses that take exactly one hour to burn, but they don’t burn at a steady rate. For example, one fuse could take 59 minutes to burn the first inch and then burn the rest of the fuse in the last minute.
How would you use these two fuses to measure 45 minutes?
Light the first fuse on both ends and the second fuse at only one end. When the first fuse burns out you know 30 minutes have passed. Light the other end of the second fuse and when it burns out, 45 minutes have passed.
I am a word of meanings three. Three ways of spelling me there be. The first is an odour, a smell if you will. The second some money, but not in a bill. The third is past tense, a method of passing things on or around.
Can you tell me now, what these words are, that have the same sound?
What has wings but can not fly. Is enclosed, but can outside also lie. Can open itself up or close itself away. Is the place of kings and queens, And doggerel of every means. What is it upon which I stand, Which can lead us to different lands?
