A particle starts from rest and traverses a distance 2𝑥 with uniform acceleration, then moves uniformly over a further distance 4𝑥 and finally comes to rest after moving a further distance 6𝑥 under uniform retardation. Assuming entire motion to be rectilinear motion, the ratio of average speed over the journey to the maximum speed on its way is
