Liam cycled to the library. He stayed at the library and then he cycled back home.
Here is Liam's travel graph.
| Time | Distance from home (km) |
|---|---|
| 09 00 | 0 |
| 09 40 | 12 |
| 10 40 | 12 |
| 11 10 | 0 |
A travel graph showing distance from home (km) on the y-axis (0 to 15) against time on the x-axis (09 00 to 11 30). The graph consists of three straight line segments: from (09 00, 0) to (09 40, 12), from (09 40, 12) to (10 40, 12), and from (10 40, 12) to (11 10, 0). The y-axis has major grid lines every 5 units and minor grid lines every 1 unit. The x-axis has major grid lines every 30 minutes and minor grid lines every 10 minutes.
