Graphs in practical situations — practice question
Michael’s route from his home to the beach is represented by the travel graph. The vertical axis gives Distance (km), marked from Home (0) up to Beach (12). The horizontal axis shows Time running from 08:00 to 11:00. A straight line climbs from 08:00 to around 09:15 and reaches 8 km, followed by a flat section up to 10:00, and then another straight line rises to 12 km at 11:00.
