Mr. Pollok Jogs once around a m circular track.  What is Mr. Pollok's:

Distance = m

Displacement =   m

Problem 2

A labrador retriever runs m in sec to retrieve a bird.  It then runs half way back in sec.  Determine the average speed and velocity of the dog.

Ave. Speed =  m/s

Ave. Velocity = m/s

Problem 3

A bus travels km South along a straight path with an average velocity of km/hr.  The bus then stops for half an hour.  It then travels km South with an average velocity of km/hr.  How long, in minutes, did the total trip last?
