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}
