Question

A submarine travels at an elevation of -75 ft relative to sea level. Then its elevation changes by 16 ft. What is the new elevation of the submarine?

A) -59 ft
B) -91 ft
C) -59 ft
D) -59 ft

Answer 1

The submarine initially at -75 ft goes up by 16 ft, resulting in a new elevation of -59 ft.

Step-by-step explanation:

The student's question involves finding the new elevation of a submarine after a change in its position. The submarine starts at an elevation of -75 ft relative to sea level. If the elevation changes by 16 ft, we must add this change to the initial elevation. So, the calculation would be -75 ft + 16 ft which equals -59 ft.

Therefore, the new elevation of the submarine is -59 ft.
