Graphs in practical situations — practice question
Ky rides from his office to a meeting and then travels back again. The travel graph illustrates the time he spends at the meeting and his return journey. Time is shown from 09:00 to 12:00 along the horizontal axis, while distance from the office (km) goes from 0 to 15 on the vertical axis. A flat section at 14 km represents the time at the meeting, followed by a straight downward-sloping line to show the journey back to the office.
