    Answer:

    • a) 2/3·m
    • b) 4/5·m

    Explanation:

    Consider the case where each part is of length 1. Then the midpoint of the first segment is at 1/2.

    a) If there are 3 segments, the midpoint of the last segment is halfway between 2 and 3, at 2 1/2. The distance from the first midpoint to the last midpoint is …

    … 2 1/2 – 1/2 = 2 . . . . . that is, 2/3 of the total line length

    When the line length is m, that is 2/3·m

    _____

    b) If there are 5 segments, the midpoint of the last segment is halfway between 4 and 5, at 4 1/2. The distance from the first midpoint to the last midpoint is …

    … 4 1/2 – 1/2 = 4 . . . . . that is, 4/5 of the total line length

    When the line length is m, that is 4/5·m
