The echo of a ships fog horn reflected from an iceber is heard 8.0 seconds after the horn is sounded How far away is the iceberg?

The sound from the ship's foghorn takes 8.0 seconds to travel to the iceberg and back. Since the sound has to travel to the iceberg and return, the time for the one-way trip is 4.0 seconds. Sound travels at approximately 343 meters per second in air, so the distance to the iceberg is 343 m/s × 4.0 s = 1,372 meters. Therefore, the iceberg is 1,372 meters away from the ship.
