Question

14) A submarine's elevation is -14 feet relative to sea level. A shark is swimmingat an elevation of -56 feet What is the difference in elevation between thesubmarine and the shark?

Answer 1

The level of the submarine is (-14 ft) that is 14 feet below sea level.

The shark is swiming at (-56 ft) that is 56 ft below sea level.

Then the difference between their elevations is calculated as the absolute value of the difference of those values:

| -14 - (-56)| = | -14 + 56 | = | 56 - 14 | = | 42 | = 42 ft

The difference in elevation is 42 ft.
