Distance-Time Graphs

Match the description to the graph:

"The car is traveling at a constant speed."

• 
• 
• 
• 

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.

Which graph (if any) shows the object moving at a constant speed, stopping, and then continuing to move in the same direction?

• 
• 
• 
• 
• none of these
