Question 12
The graph shows Clover’s distance from home. She visits a grocery store, then a park, returns towards her grandparents’ house when it rains, then cycles to a bookstore and home. Her average speed over the whole trip is 8 km/h. How long does she stay at her grandparents’ house? Chart axes: distance from home in km; time in minutes.
Route convention: each moving section follows a direct route towards or away from home, so travelled distance is the change in the plotted distance.
