Question

A diver is 40 feet below the sea level. How much below/above is he from the sea level after he swims 35 feet towards the surface?

• A. 15 feet below sea level
• B. 15 feet above sea level
• C. 5 feet below sea level
• D. 5 feet above sea level

Answer 1

The correct option is C

5 feet below sea level

If the diver is 40 feet below the sea level, he is at a height of -40 feet.
(Considering the sea level as 0 feet)

If he now swims 35 feet towards the surface, then his distance from the surface will be (-40 + 35) feet.

We know that -40 + 35 = - 5.

Thus, he is 5 feet below sea level.
