A car starts from rest and accelerates at uniform rate of 6 m s^(-2)for some time, then moves with constant speed for some time and retards at the same uniform rate and comes to rest. Total time for the journey is 24 s and average speed for journey is 20 m s^(-1) , How long does the car move with constant speed?
