- A car completes a lap of a 1,600 meter track in 55 seconds.
- What is the average speed, in metres per second?
- What is the average speed, in kilometres per hour?
- What is the average velocity, in metres per second?
- What is the average velocity, in kilometres per hour?

- In 4 seconds, a car drives 16 metres forwards.
- What distance does the car travel?
- What is the average speed of the car, in m/s?
- What is the displacement of the car?
- What is the average velocity of the car, in m/s?

- In 3 seconds, a car drives 8 metres backwards.
- What distance does the car travel?
- What is the average speed of the car, in m/s?
- What is the displacement of the car?
- What is the average velocity of the car, in m/s?

- Combining the previous 2 questions: In 7 seconds, a car drives 16 metres forwards, then 8 metres backwards.
- What distance does the car travel?
- What is the average speed of the car, in m/s?
- What is the displacement of the car?
- What is the average velocity of the car, in m/s?
