Answer 1

To find the vertical distance between Kale and the family of dolphins, you can subtract the depth of the dolphins from Kale's depth:

Kale's depth: -647 feet
Dolphins' depth: -112 feet

The vertical distance \( D \) between Kale and the dolphins is:

\[
D = (-647) - (-112) = -647 + 112 = -535
\]

The negative sign indicates that Kale is deeper below sea level than the dolphins. The vertical distance, therefore, is 535 feet.

So the correct answer is:
**535 feet**
