CSEC Mathematics · January 2004 · Paper 2 · Question 9(a)(i)

A graph represents the journey of an athlete running from a training camp to a park and back to the camp. The x-axis is Time (hr) from 04:00 to 08:00. The y-axis is Distance (km) from 0 to 10. The graph starts at (04:00, 0), rises to (06:00, 9), stays flat until (06:30, 9), then falls to (08:00, 0).

Using the graph, determine the time at which the athlete left the training camp.
