Calculate the distance and displacement in each of the following situations. Include a direction (example: north or northwest) with your answer.
David walks 3 km north, and then walks 1 km south.
Distance =Displacement =
Amy runs 2 miles south, then turns around and runs 2 miles north.
Distance =Displacement =
Jermaine runs exactly 2 laps around a 400 meter track.
Distance =Displacement =
Derrick crawls 4 feet east, and then turns east and crawls 6 west.
Distance =Displacement =
Ray runs 30 feet north and then 30 feet west.
Distance =Displacement =
