4. A plane is flying at the height of 5000 m above the sea level. At a particular point, it is exactly above a submarine floating 1200 m below the sea level. What is the vertical distance between them?
The plane is flying at the height of 5000 m above the sea level
Distance of the plane from sea level =
Also, the submarine floating 1200 m below the sea level
Distance of the submarine from sea level =
Distance between them =
