Answer:
[tex]\boxed {\boxed {\sf 12.5 \ centimeters}}[/tex]
Explanation:
We are asked to find how far a pulse travels or the distance. Distance is the product of speed and time.
[tex]d= s \times t[/tex]
The speed of the plus is 5 centimeters per second and the time is 2.5 seconds.
Substitute the values into the formula.
[tex]d= 5 \ cm/s \times 2.5 \ s[/tex]
Multiply. Note that the units of seconds will cancel each other out.
[tex]d= 12.5 \ cm[/tex]
The pulse travels 12.5 centimeters.
