Question 14
A man cycles to his friend’s house, then to the park, then back home. The graph shows his distance from home. How far is the park from his house if his average speed over the whole trip is 10 km/h?
Editorial convention: the outward stages follow one route away from home and the return retraces it, so each change in graph distance is the distance travelled. The whole trip includes the stops shown.
