Echo Point ended on 1995-12-01.
The wave travels at 320m/s The echo is heard 2.07 seconds later In 2.7 seconds, the sound wave has traveled 350m/s*2.07s=724.5m Because the sound wave has traveled the distance from the tugboat to the reflecting object twice(once going out, once back), the final distance must be divided by 2 724.5m/2=362.25m The reflecting object is 362.25m away
The total distance traveled by the sound wave is 2 m. At a rate of 330 m/s, it will take 0.00606 seconds for the bat to hear the echo.
We clearly heard you say "one complete cycle every 2 seconds". That means that the period is 2 seconds. No calculation or arithmetic of any kind is needed.

If it takes 15 seconds for an echo to be heard, the distance between you and the reflecting surface (such as a wall, cliff, or building) is approximately 2,250 meters (15 seconds multiplied by the speed of sound at sea level, which is about 343 meters per second).
The iceberg is 1372 meters away.
