Question

An underwater canyon begins at 40 feet below sea level and is 105 feet deep. what is the elevation of the bottom of the canyon

Answer 1

145 feet

Explanation:

The computation of the elevation of the bottom of the canyon is shown below;

Given that

A = sea level

B = The point at which the canyon starts

C = Canyon bottom

AB = 40 feet

BC = 105 feet

Based on the above information

The AC or elevation of the canyon bottom is

AC = AB + BC

= 40 feet + 105 feet

= 145 feet
