Question 50

A submarine sends a pulse of sound (sonar) downwards to measure the depth of the ocean floor. The sound travels through the seawater, reflects off the seabed, and is detected by the submarine again after 1.6 s. The speed of sound in seawater is 1500 m/s.

How far below the submarine is the seabed?
