    The average speed of the puck = 33.91 m/s

    Explanation:

    Speed: This is the ratio of distance to time. The S. I unit of speed is m/s.

    mathematically speed is expressed as,

    S = d/t ... Equation 1

    Where s = average speed of the puck, d = distance, t = time.

    Conversion: If 1 foot = 0.3048 m

    then, 89 feet = 0.3048*89

    = 27.13 m.

    Given: d = 89 feet = 27.13 m, t = 0.8 seconds.

    Substituting these values into equation 1

    S = 27.13/0.8

    S = 33.91 m/s

    Therefore the average speed of the puck = 33.91 m/s
