Question

A whale is at the surface of the ocean to breathe. The whale swims down 300 feet to feed. The whale swims down 150 more feet more. What is the whale’s elevation now?

Answer 1

The whale's elevation is -450. This is because 300 + 150 = 450, making the whale 450 feet below sea level.

Answer 2

0-300-150=-450 feet
-450 feet is the whale’s elevation
