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?
Could you just set light to the fuse and put it out after exactly 15 mins?
