A body starts...

Question

A body starts from rest and travels a distance $x$ with uniform acceleration, then it travels a distance $2 x$ with uniform speed, finally it travels a distance $3 x$ with uniform retardation and comes to rest. If the complete motion of the particle is along a straight line, then the ratio of its average velocity to maximum velocity is
