Answer

Explanation:

Step1: Calculate the distance

The distance from the center - line to the goal - line is half of the distance between the two goal - lines. Given the distance between the two goal - lines is $d = 54$ meters, so the distance the puck slid $s=\frac{54}{2}=27$ meters.

Step2: Calculate the velocity

The formula for velocity is $v=\frac{s}{t}$, where $s$ is the displacement and $t$ is the time. Here, $s = 27$ meters and $t = 3$ seconds. So $v=\frac{27}{3}=9$ meters per second.
