Question

A diver is 40 feet below the sea level. Then he swims 35 feet towards the surface. He is at .

• A. 75 feet
• B. -75 feet
• C. 5 feet
• D. - 5 feet

Answer 1

The correct option is D - 5 feet

If the diver is 40 feet below the sea level, he is at a height of -40 feet.

If he now swims 35 feet towards the surface, i.e., in the opposite direction, then we have - 40 + 35.
We know that -40 + 35 = - 5.
Thus, he is at -5 feet or 5 feet below sea level.
