Question

125 feet in 5 seconds as a unit rate

Answer 1

 125 feet in 5 seconds as a unit rate would be125/5 or 25/1

Answer 2

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 $125\ feet$ by $5\ seconds$

so

$\frac{125}{5}\frac{feet}{seconds} =\frac{25}{1}\frac{feet}{second}$

therefore

the answer is

$25\frac{ft}{sec}$
