A BIKE JOURNEY

A cyclist travels along a road without turning back. The graph shows the total distance travelled since the start against time. Each straight segment joins two measurements and represents a constant speed. The same measurements are given in the table.

Time (min) on the horizontal axis; distance (km) on the vertical axis. The line joins (0, 0), (10, 2), (15, 2) and (25, 5). figure

Journey measurements

Time (min)	0	10	15	25
Distance travelled (km)	0	2	2	5

During which interval does the cyclist stop? Explain how the graph shows this.

observe

Compare the cyclist’s speed from 0 to 10 minutes and from 15 to 25 minutes. Calculate each speed in km/min and relate it to the slope of each segment.

compare speeds

After 25 minutes, the cyclist keeps the speed of the final segment for another 5 minutes. What total distance will she have travelled at 30 minutes?
