Answer: The whale is 438 meters below the sea level.
Explanation:
Given: A whale is hunting at an elevation of −438 meters relative to sea level.
Since in the scenario of height, a positive integer is used to represent the height (above a particular level) whereas a negative integer is used to represent the depth ( below a particular level).
If the whale is hunting at an elevation of −438 meters relative to sea level, then this means that the depth between the whale and the sea level is 468 meters.
Hence, the whale is 438 meters below the sea level.
