Question

What is the final elevation if a diver starts at 5 m and changes -16 m?Hi, I need help with this question above. Brainly has 2 different answers. One states 21 m and the other states -21 m. And I think the answer is -11 m?My math teacher said there is some easy way to do this- to find the elevation. Please help and thank you

Answer 1

First step: Let's illustrate this problem as follows.

So the final answer is -11.

NOTE: -16m of change means he is going down.

-11 means the elevation is -11 m under the water once we consider the surface of the water is 0 m.
