A distance-time graph of a person walking shows distance $0$ km at $t=0$, $2$ km at $t=1$ h and $4$ km at $t=2$ h. The motion is best described as:
- Stationary
- Uniform speed of $2$ km/h
- Accelerating
- Decelerating
Solution
Equal distance ($2$ km) per hour gives a straight line with slope $2$, i.e. uniform speed of $2$ km/h.
