Time Distance Graphs

What is a plausible description of this graph?

• The object began moving away quickly at a constant speed. It stopped. It then turned to return at a constant speed.

• The object changed diections three times.

• The object began walking away slowly then began running away. Both were at constant speeds. It then turned and walked back to where it started.

• The object began moving away at a constant speed. It continued moving away, but slowed its speed. It then turned around and returned home at a speed that was probably in between the first two speeds.

At 60 seconds, how far had this object traveled? 

• 0 m

• 10 m

• 20 m

• 40 m
