    39428.93 N/m²

    Explanation:

    Pressure: This can be defined as the force acting normally perpendicularly per unit area of surface. The S. I unit of pressure is N/m²

    The pressure in a fluid is given as

    P = ρgh ... Equation 1

    Where P = pressure, ρ = density, h = height, g = acceleration due to gravity.

    Note: The North Atlantic is an ocean, and it contains water

    Given: h = 2.5 mile

    If 1 mile =

    1 609.344 meters,

    Then 2.5 miles = (1609.344*2.5) m = 4023.36 m.

    Constant: g = 9.8 m/s², ρ = density of water = 1.0 g/m³

    Substituting these values into equation 1

    P = 1*4023.36*9.8

    p = 39428.93 N/m²

    Thus the pressure at that depth = 39428.93 N/m²
