Question 15
The graph shows Clover’s distance from home. She visits a grocery store, then the park, returns to her grandparents’ house because of rain, cycles to a bookstore, and cycles home. Her average speed over the entire recorded time is 8 km/h. How long does she stay at her grandparents’ house?
Editorial convention: all travel follows one route, so a change in the plotted distance gives the distance travelled on that segment. The equal horizontal grid intervals represent equal times.
