text: Q:
  
  CLLocationManager class
  
  can CLLocationManager class be used to compute the distsnce travelled by the person?
  
  A:
  
  No, but CLLocation objects can.  If you have two locations, then you can easily use the -[CLLocation distanceFromLocation:] method to get the distance between them.  Note, however, that this distance will be from along a great circle ("as the crow flies"), and not along any roads in the area.
