You have a lighter and two ropes. Each rope burns up in 60 minutes from end to end. The ropes do not burn evenly, however, so you cannot assume that half the rope burns in 30 minutes, or that X percent of the rope burns in X percent of the time. How can you measure 45 minutes?

First arrange the two ropes A and B so you are holding all four of the rope ends. At the start, light both ends of rope A and one end rope B. Exactly when rope A burns up, light the other end of rope B. The time from the start to when rope B burns up is exactly 45 minutes.

To see why, first note that it takes rope A exactly 30 minutes to burn up. Intuitively this makes sense. If rope A burns in 60 minutes with one flame, then it would burn in 30 = 60/2 with two flames. After 30 minutes, some amount of rope B is left. By similar logic, it will take 15 minutes to burn what remains of rope B with two flames.

Therefore, the total time to burn both ropes is 30 + 15 = 45 minutes.
