Answer :
Final answer:
The depth of the ocean is 750 meters.
Explanation:
To determine the depth of the ocean, we can use the formula:
Depth = Speed of sound * Time taken for echo to return
In this case, the speed of sound is given as 1500 m/sec and the time taken for the echo to return is 0.5 seconds.
Substituting the values into the formula:
Depth = 1500 m/sec * 0.5 sec = 750 meters
Therefore, the depth of the ocean at that point is 750 meters.
