2. a. a fish is 12 meters below the surface of the ocean. what is its elevation?
b. a sea bird is 28 meters above the surface of the ocean. what is its elevation?
c. if the bird is directly above the fish, how far apart are they?

A. -12 meters

B. 28 meters

C. 40 meters

Step-by-step explanation:

The surface of the ocean would be 0.

Taking this into account, 12 meters below would be 0 - 12, which is -12. Therefore A's elevation would be -12.

For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.

Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.
