Sam drove to a farm. He stayed at the farm and then he drove back home.
Here is Sam's travel graph.
| Time | Distance from home (km) |
|---|---|
| 10 00 | 0 |
| 10 45 | 30 |
| 11 30 | 30 |
| 12 30 | 0 |
A travel graph showing distance from home (km) on the y-axis (0 to 40) against time on the x-axis (10 00 to 12 30). The graph consists of three straight line segments: from (10 00, 0) to (10 45, 30), from (10 45, 30) to (11 30, 30), and from (11 30, 30) to (12 30, 0). The y-axis has major grid lines every 10 units. The x-axis has major grid lines every 15 minutes.
For how many minutes did Sam stay at the farm?
What was Sam's average speed on his journey to the farm?
