Under which of the following conditions is the magnitude of the average velocity of a particle moving in one dimension smaller than the average speed over the time interval?
  1.A particle moves in the +x direction and then reverses the direction of its motion.
  2.A particle moves in the -x direction without reversing.
  3.There are no conditions for which this is true.
  4.A particle moves in the +x direction without reversing.
