Question

If the submarine rises 200 feet towards sea level, which integers represent its movement and new position in relation to sea level, respectively?

A) 200 and 300
B) 200 and −300
C) −200 and 300
D) −200 and −300

Answer 1

The movement of the submarine towards the surface by 200 feet is represented by the positive integer +200. The new position cannot be accurately determined without knowing the submarine's initial depth below sea level.

Step-by-step explanation:

To answer this question, we need to remember that depth below sea level is usually represented by negative integers, and movement towards the surface is considered an upward, or positive, change in position. If the submarine rises 200 feet towards sea level, this is a positive change. However, we don't know the submarine's initial position in the question, only its movement. Therefore, we cannot accurately give the new position without additional information. Generally, the integer representing its movement is +200, indicating an upward movement. If we assume that the new position is meant to reflect its position after this movement and the initial position was -500 feet, then the new position would be -300 feet. But without knowing the starting depth, we cannot determine the exact new position; we can only state the movement as a positive integer.
