A hat trick is a hockey term that refers to a player scoring 3 goals in a game. If a player scores fifteen hat tricks in their career, how many total goals does that represent?

Correct answer:

45 Goals

Since a hat trick is three goals and the player has recorded fifteen of them, that is a total of 45 (15 x 3) goals.

In order to stay frozen, the ice surface of a hockey rink cannot be above what temperature?

Correct answer:

32° Fahrenheit /
0° Celsius

The freezing point of water is the temperature at which water changes phase from a liquid to a solid. To maintain the ice on a rink, the ice temperature must be at or below the freeezing point of 32° Fahrenheit / 0° Celsius. The ice on most NHL hockey rinks is typically between 22° and 25° Fahrenheit or -4° to -6° Celsius.

If an average NHL player skates approximately 5 miles / 8 kilometers per game, what total distance will they skate if they play in each of the 82 regular season games?

Correct answer:

410 miles /
660 KM

By multiplying the distance skated per game (5 miles / 8 KM) by the number of games (82), we can determine that a player will skate approximately 410 miles in a season.

Each hockey skate has a blade that is comprised of two sharp edges. The space between these two edges is called the hollow. If a convex surface curves outward and concave surface curves inward, what kind of surface is the hollow of a skate?

Correct answer:


Since the hollow of the skate blade curves inward, it is a concave surface. NHL hockey players can select a variety of hollow depths depending on their skating style and personal preference. A shallow hollow allows for more speed and glide, while a deeper hollow creates greater grip or ‘bite’ on the ice.

Each face-off circle on the ice has a diameter of 30 feet / 9.1 metres. What is the radius of these face-off circles?

Correct answer:

15 feet /
4.5 metres

The diameter of a circle is straight line going through the center of a circle connecting two points on the circumference . The radius of a circle is the distance from the center of the circle to the outside edge. If a circle has a diameter of 30 feet or 9 metres, then the radius is 15 feet or 4.5 metres.

An NHL Goaltender will face an average of 30 shots in a game. If a goalie allows 3 goals out of 30 total shots, what is the average goalie’s save percentage?

Correct answer:


Since the goaltender saved 27 of 30 shots, that means that the goalie’s save percentage was 27 divided by 30 or 90%

If an obtuse angle is one that is more than 90 degrees and and an acute angle is less than 90 degrees, which kind of angle is represented in this hockey stick?

Correct answer:


The angle that the blade makes contact with the shaft is called the lie. As evidenced in the image, the lie of a hockey stick is greater than 90 degrees and thus it forms an obtuse angle. Most hockey sticks have a lie of approximately 135 degrees.

If a puck is shot at a goalie from 60 feet away at a speed of 90 mph, then the goalie has a reaction time of 0.45 seconds before the puck reaches the goal. If another shot is taken at the same speed from 30 feet away, will the goalie’s reaction time increase or decrease?

Correct answer:


A goalie’s reaction time is measured by dividing the distance from which the shot is taken, by the speed of the shot. Since the second shot is taken from a closer distance than the first, the goalie’s reaction time would decrease.
