You are in a windowless room with one door and 4 light switches in the off position. One of the switches controls a light bulb in another room which you cannot see. The other three switches do nothing. You may manipulate the switches however you wish, but once you leave the switch room to go to the light bulb room you cannot go back. How can you determine which switch controls the light bulb?

Two trains are moving toward each other on the same track, each traveling at 25 mph. When they are 100 miles apart a fly starts at the front of the first train and flies toward the second at 37 mph. When it reaches the second train it instantly reverses direction and flies back toward the first, again at 37 mph. It continues in this manner, flying back and forth between the trains at 37 mph until the trains collide and the fly is squished. How far does the fly fly?
