The diagram shows the distance-time graph for a car. At which labelled point is the car moving with constant speed?

• A

• B

• C

• D

The graph shows how the distance travelled by a vehicle changes with time. Which row describes the speed of the vehicle in each section of the graph?

• A

• B

• C

• D

Match the distance-time graphs to the description.

• stationary

• 
• decelerating

• 
• accelerating

• 
• constant speed

The distance–time graph shows the motion of an object over a 120-second period. Calculate the object’s average speed in m/s.

• 0.3334

• 0.6667

• 1.3334

• 1.6667

Which statement best describes the motion of the object shown in the distance-time graph?

• The object is at rest, then moves at a constant speed before coming to rest again.

• The object moves at a constant speed then moves at a higher constant speed.

• The object moves at a constant speed, stops, then continues at a slower constant speed.

• The object moves at a constant speed, stops, then continues at a faster constant speed.

Match each distance-time graph with the description that best represents the motion shown.

• constant speed then acceleration

• 
• constant speed then deceleration

• 
• acceleration then constant speed

• 
• acceleration then deceleration

• 

The figure shows a distance-time graph. Arrange the descriptions of the object’s motion in chronological order.

• constant speed of 6 m/s

• stationary for 3 seconds

• constant speed of 5 m/s

• stationary for 4 seconds

• constant speed of 2 m/s

In a race, a car travels 60 times around a 3.6 km track. This takes 2.4 hours. What is the average speed of the car?
