    Answer:

    t = 0.051 seconds

    Explanation:

    Given that,

    A skydiver jumped out of a plane and fell 9 miles to the ground. It means 9 miles is the distance covered.

    The average speed of the skydiver is 174 miles/hour

    We need to find the time for which he dive last. It means t is the time taken. Total distance covered divided by time taken is called average speed. So,

    v=\dfrac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{9}{174}\\\\t=0.051\ s

    So, a skydiver dive for 0.051 seconds.
