Data:
Distance: 1/2 mile
Time: 8 and 1/2 minutes
The unit rate in miles per minute is the number of miles that George walked in a minute. Then, to find the rate in miles per minute:
1. The rate is the relation betwwen the distance and the time, and ollows the next formula:
[tex]r=\frac{d}{t}[/tex]Where r is the rate, d is the distance and t is the time.
Then we use that formula and the given values of d and t to find the rate:
[tex]r=\frac{\frac{1}{2}\text{miles}}{(8+\frac{1}{2})\min }[/tex]We can do first the add in the denominator:
[tex]8+\frac{1}{2}=\frac{16+1}{2}=\frac{17}{2}[/tex]Then we have that:
[tex]r=\frac{\frac{1}{2}}{\frac{17}{2}}[/tex][tex]r=(\frac{1}{17})\frac{miles}{\min}\approx0.06\frac{miles}{\min }[/tex]The rate in miles per minute is: 1/17 miles/min or approx. 0.06miles/min
