Interpreting Graph

What is happening in this graph from point A to B? HINT: Look at the axis labels. 

• The object is accelerating.

• The object is not moving.

• The object is decelerating.

• The object is moving at a constant speed.

What is happening in the graph between 30 and 40 minutes?

• Sarah is accelerating

• Sarah is not moving

• Sarah is slowing down

• Sarah is travelling at a constant speed

What is happening at D?

• Stationary

• Accelerating

• Fast steady speed; moving away from the starting position

• Slower steady speed; moving away from the starting position

This question has two parts.

A student rode his bicycle from his home to a park.

• He rode home from the park following the same route.

• He took two rest breaks during his ride, including one at the park.
