    Answer:

    2 0.00130719 m/s

    Explanation:

    Now we have

    7.86 furlongs/fortnight

    7.86 x 220 yards / fortnight

    1729.2yards / fortnight

    1647.8 yards / 14 days

    123.5yards / day

    So

    123.5 x 0.9144 meter / day

    112.meters / day

    =112.9meters / 86400s

    = 0.001307m/s
