Sassafras root is still used to flavor traditional root beer, although since sassafras was banned by the U.S. Food and Drug Administration because of the carcinogenicity of its constituent safrole, most commercial recipes do not contain sassafras. Some commercial root beers do use a safrole-free sassafras extract.
There are usually 18 holes in a golf course; some have 9 holes or some multiplier of 9 holes. I have played at golf clubs with 9, 18, 27 and 36 holes. However, a standard round of golf at most golf clubs / courses involves 18 holes.
Hole-by-Hole. A normal golf hole will take a group of professionals or a group of average amateurs around 10 to 15 minutes. This is why courses schedule tee times every 10 minutes. This equals an 18-hole round of 3 1/2 to 4 1/2 hours.he speed of a round of golf depends on the skill of the player, the traffic of the course, the size of the course, the size of the group and the mode of moving around the course. Golfing 18 holes averages around four hours for average players.
