Question

A submarine is running at a depth of 235 ft underwater. It changes course and rises 101 ft. What is the change in elevation?

Answer 1

The change in elevation is -134 ft

Explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft
