  1. well 2/3 of the distance is 1584 meters
    so
    (2/3) d = 1584
    d = (3/2)1584 meters

    total time = 12+4 = 16 minutes
    16 minutes = 16 * 60 seconds
    so
    v = d/(16*60) meters/ssecond

  2. A. 2d/3 = 1584.
    d = 2376 m.

    B. V1 = (2376/3)/4min = 198 m/min. = Velocity for 1st 4 min.
    V2 = 1584/12 = 132meters/min. = Velocity for last 12 min.
    Vavg. = (198+132)/2 = 165 m/min = 2.75 m/s.
