The answer to the question
This is an example of the quotient of powers property and tells us that when you divide powers with the same base you just have to subtract the exponents.

<em><u>Solution:</u></em>
Given that, Suzanna walked two over seven of a mile in two over five of an hour
We have to find the unit rate in miles per hour
Unit rate means number of miles covered in 1 hour
From given information,
Two over seven of a mile in two over five of an hour
Which means,


To find for number of miles covered in 1 hour, divide the 

Two sevenths over two fifths = five over seven mile per hour
Thus unit rate is 5 over 7 miles per hour
