Explanation:
Let the depth of sea be x.
Given that the sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.
Time taken to hear an echo t=1.6 s
Therefore, 2x = vt
Hence, we have 2x =1500m/s × 1.6s
=> 2x = 2400
⟹ x = 2400 ÷ 2
= 1200m
Hence, the final answer is 1200m
