It is given in the question that a parade traveled 9 miles in 3 minutes.
Here distance is 9 miles and time is 3 minutes.
We have to find how many miles travelled per minute. It means , we have to find the speed, and the formula of speed is
[tex]speed = \frac{distance}{time}[/tex]
Substituting the values of distance and time, we will get
[tex]speed = \frac{9}{3} miles/minutes[/tex]
[tex]speed = 3 miles/minutes[/tex]
Therefore the parade travelled 3 miles per minute .
