The velocity-time graph has three stages: 0 - 10s: constant \(12 \, \text{m/s}\) 10 - 14s: deceleration from \(12 \, \text{m/s}\) to \(0 \, \text{m/s}\) (last stage) The area of the triangle gives the distance in the last stage: \(\text{Area} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times (14 - 10) \, \text{s} \times 12 \, \text{m/s}\) \(= \frac{1}{2} \times 4 \times 12 = 24 \, \text{m}\).
