Question

A submarine is 730 m below sea level. An airplane that is directly over the submarine is 9,144 m above sea level. What is the vertical distance between the submarine and the airplane?

Answer 1

Submarine: -730
Airplane: 9,144
|-730-9,144|=|-9,874|=9,874
|d|: absolute value
The vertical distance between the submarine and airplane is 9,874 meters.

Answer 2

9,874 meters.

Explanation:

We have been given that a submarine is 730 m below sea level. This means that altitude of the submarine would be
`-730\text{ m}`.

We are also told that an airplane that is directly over the submarine is 9,144 m above sea level. The altitude of the airplane would be
`9,144\text{ m}`.

To find the vertical distance between the submarine and the airplane, we will subtract elevation of submarine from elevation of airplane as:

`\text{The vertical distance between the submarine and the airplane}=9,144\text{ m}-(-730\text{ m})`

`\text{The vertical distance between the submarine and the airplane}=9,144\text{ m}+730\text{ m}`

`\text{The vertical distance between the submarine and the airplane}=9,874\text{ m}`

Therefore, the vertical distance between the submarine and the airplane would be 9,874 meters.
