Addition of Velocities - Solution

  1. D.
  2. F.
  3. K.
  4. The separation between A and D is one half of the separation between A and K. Therefore, the speed of the tree is (1/2)c.
  5. The separation between A and F is four fifth of the separation between A and K. Therefore, the speed of car 2 is (4/5)c.
