    dP/dt = 0.3003003003

    Explanation:

    speed of submarine = 3m/s

    rate of change of pressure with depth = (105 Pa) per 10 meter of depth

    to get time taken by the submarine to cover 10m; t = 10/3 = 3.33s

    time rate of change of pressure = dP/dt = 105 Pa/3.33

    = 30030.03003or 0.3003003003
