| 08 20 | 15 |
| 09 40 | 15 |
| 10 10 | 0 |
A travel graph showing distance from home (miles) on the y-axis (0 to 20) against time on the x-axis (08 00 to 10 10). The graph consists of three straight line segments: from (08 00, 0) to (08 20, 15), from (08 20, 15) to (09 40, 15), and from (09 40, 15) to (10 10, 0). The y-axis has major grid lines every 5 units. The x-axis has major grid lines every 20 minutes.
