The table gives the distance covered by a car in each $2\,\text{s}$ interval over a $12\,\text{s}$ period of its journey. Which statement describes the car's motion?
- Amoving with constant speed from $0$-$4\,\text{s}$, followed by non-uniform acceleration
- Bmoving with constant speed from $0$-$4\,\text{s}$, then uniform acceleration
- Cat rest from $0$-$4\,\text{s}$, then non-uniform acceleration
- Dat rest from $0$-$4\,\text{s}$, then uniform acceleration
