A spelunker (cave explorer) drops a stone from rest into a hole. The speed of sound is 343 m/s in air, and the sound of the stone striking the bottom is heard 3.87 s after the stone is dropped. How deep is the hole?

    d = 343m/s * 3.87s = 1327.4m.

    Wrong. Not all of the 3.87 seconds is sound travel time. Most of it isnt
