Pace of play is controlled by two key factors, the number of shots you take to play the round and the time you take in between your shots. If someone shoots 100 and takes 45 seconds per swing that only accounts for 75 minutes. The rest of the time is taken traveling between your shots or waiting for others to hit. Pay attention to your partners shot, assess your shot long before it is your turn to swing and write your scores down while you wait on the next tee. Last but not least always be within a swing of the group in front of you.
