Answer: $-64\frac{2}{7}\text{ feet}$

Step-by-step explanation:

When the scientists detect a signal frequency from the ocean floor, then the depth of submarine = $-116\frac{2}{7}$ feet

= $-\frac{814}{7}$ feet

When they dive farther to check the signal, then the depth of the submarine= $-180\frac{4}{7}=-\frac{1264}{7}$ feet.

The net change in their elevation = $-\frac{1264}{7}-(-\frac{814}{7})$

$=-\frac{1264}{7}+\frac{814}{7}\\=-\frac{450}{7}=-64\frac{2}{7}\text{ feet}$
