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 \(\rm{}= 6200m.\)
