Plausible

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.

What is a plausible story for this graph?

• A student was jogging from school to home. She stopped to tie her shoe and take a drink from her water bottle, then continued at the same pace as before.

• A student was jogging from school to home. She walked for a while, then continued jogging.

• A sled rider was going down a hill. The hill was steep at first, then kind of flat. At the end, it was steep again.

• A car was slowing down, then contued moving at a constant rate. Finally, it slowed to a stop,
