The bus moves at a steady speed, pauses for a short interval, and then continues at a faster steady speed. On the axes in Fig. 1.1, sketch a distance-time graph for this bus journey. Fig. 1.1 shows axes labelled distance on the vertical axis and time on the horizontal axis, with both axes starting at 0.
