Question
In international play hockey puck is struck by a "green team" hockey player at the blue line with 2:35 on the clock. It is stopped by an "orange team" player at the opposite blue line with 2:32 on the clock. On an international hockey rink the blue lines are 17⅔ m apart. Calculate the speed of the hockey puck.

To calculate the speed of the hockey puck, we need to determine the distance it traveled and the time it took to travel that distance.

1. **Distance**: The distance between the two blue lines is given as 17⅔ meters. This can be converted to a decimal:
\[
17 \frac{2}{3} = 17 + \frac{2}{3} = 17 + 0.6667 \approx 17.6667 \text{ meters}
\]

2. **Time**: The puck was struck at 2:35 and was stopped at 2:32. Therefore, the time it took for the puck to travel from the blue line to the other blue line is:
\[
2:35 - 2:32 = 3 \text{ seconds}
\]

3. **Calculating Speed**: Speed is calculated using the formula:
\[
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
\]
Substituting in our values:
\[
\text{Speed} = \frac{17.6667 \text{ m}}{3 \text{ s}} \approx 5.8889 \text{ m/s}
\]

Thus, the speed of the hockey puck is approximately **5.89 m/s**.
