Answer 2

Diver descended 43 feet from the rock to the coral reef.

Explanation:

Given : A deep sea diver descended from a rock that is 45 feet below sea level to a coral reef that is 88 feet below sea level.

To find : How far did the diver descend from the rock to the coral reef.

Solution : We have given

A deep sea diver descended below sea level = -45 feet .

A coral reef that is 88 feet below sea level = -88 feet.

Because we take the negative value below sea level( 0 ).

Difference = -45 - ( - 88)

Difference = -45 + 88 = 43

Diver descended 43 feet from the rock to the coral reef.

Therefore, Diver descended 43 feet from the rock to the coral reef.
