Sketch the motion. The graphs answer.
Drag the position points (or focus one and use ↑ ↓). The velocity–time graph below is computed from your sketch — it can never disagree with it.

Walk east at 1 m/s for 4 s, stand still for 4 s, then walk east at 1.5 m/s for 2 s.
What your sketch says
- displacement
- 0 m
- distance travelled
- 0 m
- average velocity
- 0 m/s
- average speed
- 0 m/s
Leg by leg
- 0 s to 2 s: at rest at 0 m from start
- 2 s to 4 s: at rest at 0 m from start
- 4 s to 6 s: at rest at 0 m from start
- 6 s to 8 s: at rest at 0 m from start
- 8 s to 10 s: at rest at 0 m from start
Position–time (+ is [E])
Velocity–time (computed from your sketch)
Steeper position line ⇒ taller velocity step. A downhill leg sits below zero: negative velocity is motion [W].
