A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 15 times the speed of sound in air. A Woman, at the other end with her ears close to the rod hears the sound of the blow twice with a 0.12 s interval between; one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 343 m/s, what is the length of the rod?
