Answer:
[tex]\boxed {\boxed {\sf 6 \ meters \ per \ second}}[/tex]
Explanation:
Speed can be found by dividing the distance by the time.
[tex]s=\frac{d}{t}[/tex]
The distance is 18 meters and the time is 3 seconds.
[tex]d= 18 \ m \\t= 3 \ s\\[/tex]
Substitute the values into the formula.
[tex]s=\frac{18 \ m }{ 3 \ s }[/tex]
Divide.
[tex]s= 6 \ m/s[/tex]
The speed of the puck is 6 meters per second.
