The diagram shows a speed-time graph of a car.

- Calculate the distance the car travels from rest before it begins to decelerate.

Which part of the above graph represents the acceleration of the car?

How is the distance the car travels represented?

- Given that the car decelerates at \(\quantity{0.5} {m/s^2}\), calculate the total time taken for the journey.

Can we find the equations of the straight line parts of the graph?

How can you use this to compute the total time taken for the journey?
