A hungry penguin was swimming 21

Feet below sea level it swam up 9 feet to eat a fish what is the position of the penguin now relative to sea level

1 answer

To find the penguin's position relative to sea level, we start with its initial position, which is 21 feet below sea level. We can represent below sea level as negative:

-21 feet (initial position)

The penguin then swims up 9 feet. To find the new position, we add 9 feet to the initial position:

\[ -21 + 9 = -12 \]

The penguin is now at -12 feet, which means it is 12 feet below sea level.
