$16 , 854$ feet

#### Explanation:

We need to find the distance between these elevations. The word 'difference' indicates it is a subtraction.

(Below sea level can be shown as a negative number.)

$16 , 612 - \left(- 242\right)$

$= 16 , 612 + 242$

$= 16 , 854$ feet

Note that you end up adding because the elevations are on opposite sides of Sea level - one above and the other is below.
