    Answer:

    Hₐ (airplane) =  H₀ +25,000

    Hₐ (submarine) =  H₀ -600

    Difference in elevation = 25,600 ft

    Step-by-step explanation:

    Let the reference point  be Sea level

    Let the Height at sea level = H₀

    Let the height above or below sea level = H₁

    Total Height  with respect to sea level = Hₐ

    Hₐ =H₀ ±  H₁——————————————————————— (1)

    Where:  

    (+) is used for height above sea level

    (-) is used for height below sea level    

    For the airplane :

    Hₐ (airplane) =H₀ + H₁

        = H₀ + 25,000—————————————————– (2)

    For the Submarine;

    Hₐ (submarine)  =H₀ – H₁

        =H₀ -600

    Summarily:

    Hₐ (airplane) =  H₀ +25,000

    Hₐ (submarine) =  H₀ -600

    H₀ is common in both expressions for the respective heights. The difference  in elevation is given by :

    Hₐ (airplane) -Hₐ (submarine) =   (H₀ +25,000 ) -(H₀ -600)

                                                    = 25,600 ft
