    First, convert the ft to standard units of meters.

    1 foot = 0.3048 meters

    Therefore,

    484 ft = 147.5232 meters

    Then, we will use the laws of motion to calculate the time:

    x = 0.5 at^2

    where:

    x is the displacement

    a is the gravity (9.8 m/sec^2)

    t is the time taken

    Substitute in the equation with the givens to calculate the time as follows:

    147.5232 = (0.5 x 9.8) t^2

    t^2 = 147.5232 / (0.5 x 9.8)

    t^2 = 30.11 seconds

    t = 5.49
