A submarine is cruising at a depth of 108 feet. Assume the body of water is at sea level. How can you describe the elevation of the submarine? Check all that apply.

Question

108 above 0
108 below 0
–108 below 0
108
–108
+108

Answer 1

To describe the elevation of the submarine cruising at a depth of 108 feet below sea level, you can use the following options:

• 108 below 0: This means that the submarine is 108 feet below sea level.
• –108 below 0: This is the same as stating that it is 108 feet below sea level, using a negative sign to indicate below sea level.
• –108: This is another way to express the submarine's elevation as being 108 feet below sea level.
• 108: This is ambiguous without context, as it doesn't specify if it's above or below sea level.
• +108: This implies 108 feet above sea level, which is not applicable to the submarine's position.

So the applicable descriptions from your list are:

• 108 below 0
• –108 below 0
• –108
