To find the depth of the sea based on the information provided, we can follow these steps: ### Step 1: Identify the given data - Speed of sound in water (v) = 1600 m/s - Total time for the sound to travel to the seabed and back (t) = 3 s ### Step 2: Calculate the time taken for the sound to reach the seabed Since the total time includes both the journey to the seabed and the return journey, the time taken to reach the seabed (t_depth) is half of the total time: ...
