Question

A diver is 20 feet below sea level. An integer to represent the situation is _________ 

  1. 20
  2. 10
  3. -20
  4. -10

hintHint:

The sea level is marked at zero. If you below the sea level, the distance would be marked as negative or else positive.

The correct answer is: -20


    Given that a diver is 20 feet below the sea level. We know that sea level is marked at 0. So, if we go under the sea by x feet, then it would be marked as - x feet. Thus, we have 20 feet below the sea level marked as - 20 feet
    Hence, the correct answer is option c.
