Question

A submarine, initially 255 feet below sea level, descends 75 feet and then ascends 153 feet. What represents the location of the submarine compared to sea level?

A. 27 feet above sea level
B. 75 feet below sea level
C. 78 feet below sea level
D. 153 feet above sea level

Answer 1

The submarine is located 78 feet below sea level.

Step-by-step explanation:

The submarine initially starts at 255 feet below sea level. It then descends further by 75 feet, which means it is now at a depth of 255 + 75 = 330 feet below sea level.

After that, it ascends by 153 feet. So the total change in depth is 75 - 153 = -78 feet.

This means the submarine is currently located 78 feet below sea level, which corresponds to option C.
