How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible?

Newton’s first law says a moving puck keeps moving at the same speed and direction unless an unbalanced force acts on it. A rough surface creates more friction opposing the puck’s motion, slowing it down. Smooth ice reduces that opposing force, so the puck can travel quickly; this matches “Smooth ice reduces the unbalanced forces that would slow the hockey puck.”
