Which of the following situations corresponds to this graph?

• A car, accelerates from a stop,travels at a constant speed, slows,
  and then travels at a slower speed.

• An airplane travels at a constant
  speed then decelerates to a slower speed.

• An athlete warms up by walking
  around the track, runs, then jogs.

• A bicyclist accelerates, travels at a
  constant speed, then slows to a
  stop.
