we know that
Unit Rate is the ratio of two measurements in which the second term is one
In this problem to find the unit rate divide [tex]125\ feet[/tex] by [tex]5\ seconds[/tex]
so
[tex]\frac{125}{5}\frac{feet}{seconds} =\frac{25}{1}\frac{feet}{second}[/tex]
therefore
the answer is
[tex]25\frac{ft}{sec}[/tex]
