Diagram Description
Distance-Time Graph
The graph shows distance (in km) on the vertical axis and time (in hours) on the horizontal axis. The curve starts at the origin (0,0), rises steeply at first, then the slope decreases gradually.
| Time (hours) | Distance (km) |
|---|---|
| 0 | 0 |
| 1 | 60 |
| 2 | 100 |
| 3 | 120 |

Calculate Estimate the speed of the car at t = 2 hours by finding the gradient of the tangent to the curve at that point.
