## Text Solution

What is known?

Distance of plane and submarine from the sea level

What is unknown?

The vertical distance between plane and submarine.

Steps:

Height of the plane above the sea level $$= 5000 \rm\,m$$

Depth of submarine below the sea level $$= \,–1200 \rm\,m$$

Distance between plane and submarine

\begin{align}& = 5000\rm{}\,\, m -\left( \rm{}-1200\, m \right)\\\rm{} &= 5000 + 1200\\& = 6200\rm{} m\\{\rm{}}\end{align}

Hence, the vertical distance between $$\rm{}= 6200m.$$
