Kinematics of a driving car

  1. Feb 19, 2006 #1
    two road rally checkpoints A and B are located on the same highway and are 8046.72m apart.the speed limit for the first (A to C ) is 3106.86m and the last (C to B) is 1864.11m are 26.82m/s and 15.65m/s respectively . driver must stop at each checkpoint and the specific time between point A and point B is 620s.knowing a driver acce and decelerates at the same constant rate,determine the magnitude of her acceleration if she travels at the speed limit as much as possible.

    the answer is 2.0634m/s^2
    pls help

    Is 3106.86m refering to the distance between A and C?
