Read the description of a cyclist’s journey and plot a distance-time graph on the axes below. A cyclist began a race with a steep, uphill climb of 5km. It took half an hour to reach the top. The terrain levelled out and the cyclist travelled a further 15km in half an hour before they fell off their bike. The cyclist had to wait for 30 minutes to be checked by their medical team before continuing on their journey. The cyclist had no severe injuries and was able to complete the final 40km of the race in exactly one hour. 60 55 50 45 Distance (km) 40 35 30 25 20 15 10 5 0 0 0.5 1 1.5 2 2.5 Time (hours) 2 of 2
