An object accelerates uniformly from rest to speed $v$. It then moves at constant speed $v$ for a time of 8.0 s before decelerating uniformly to rest. The total time taken is 12.0 s, and the total distance travelled is 60 m. What is the speed $v$?

1. A3.0 m s⁻¹
2. B5.0 m s⁻¹
3. C6.0 m s⁻¹
4. D15 m s⁻¹
