    Answer:

    Length of minutes hand= 1.5 feet

    Height of the center of the clock from the ground= 8 feet

    Step-by-step explanation:

    At 12:15, the end of the minute hand of a clock is 8 feet above the ground.

    At 12:15 the minutes hand is making a radius along the diameter of the clock which means it is at the center of the clock. In other the center of the clock is 8 feet above the ground.

    At 12:30, it is 6.5 feet off the ground .

    This tells length of the minutes hand the clock which is the distance from the ground minus the distance off the ground

    = 8-6.5= 1.5 feet

    The center of the clock is 8 feet from the ground.
