Question

Hi there, everyone on Brainly has a different answer for this question below (some say the answer is 21 m and others say it is -21 m??). I thought the answer would be -11 m. But I seem to remember my math teacher saying that there is some trick to inverting the numbers or something? What is the correct answer please and why? Thank you!!QUESTIONWhat is the final elevation if a diver starts at 5 m and changes to -16 m?

Answer 1

The final elevation of the driver can be given as,

$h=h_2-h_1$

Here, h is the final elevation, h2 is the final distance and h1 is the initial distance.

Substitute the known values,

$\begin{gathered} h=-16\text{ m-5 m} \\ =-21\text{ m} \end{gathered}$

Thus, the final elevation of the diver is -21 m.
