The table shows the velocity of a lift as it moves between two floors.
Table
| Time (s) | Velocity (m/s) |
|---|---|
| 0 | 0 |
| 4 | 8 |
| 10 | 8 |
| 14 | 0 |
The velocity changes at a steady rate between each pair of readings.
What is the total distance travelled by the lift?
48 m48\ \text{m}48 m
80 m80\ \text{m}80 m
96 m96\ \text{m}96 m
112 m112\ \text{m}112 m
