Explanation:
Got it right on EDG ;P
Good luck!
It is important to keep the ice smooth on a hockey rink because this reduces the unbalanced forces that would slow the hockey puck.
Frictional forces
Frictional forces are opposing forces to the motion of an object on a platform.
In order to be able to pass a puck as quickly as possible on a hockey rink, there should be a minimal frictional force on the ice surface on which the puck moves.
With minimal opposing forces, the puck will move as unhindered as possible and passing as fast as possible would be easy.
