    1,700feet

    Explanation:

    If an object in free fall travels a distance s that is directly proportional to the square of the time t, this can be represented mathematically as;

    S = kt²where;

    k is the proportionality constant

    K = s/t²

    s1/t1² = s2/t2² = Sn/tn² = k for values of the distance and time. Using the formula

    s1/t1² = s2/t2² where;

    s1 is the falling distance in time t1 s2 is the falling distance in time t2

    Given s1 = 1088feet, t1 = 8secs, s2 = ? t2 = 10secs

    Substituting this value in the formula to get s2, we have;

    1088/8² = s2/10²

    64s2 = 108800

    s2 = 108800/64

    s2 = 1,700feet

    This means the object will fall a distance of 1,700feet in 10seconds
