Answer:
Step-by-step explanation:
Set this up as a ratio of minutes to miles. If it takes her 24 minutes to run 3 miles, the ratio that expresses that is
[tex]\frac{24}{3}[/tex]
If you want to find out how long in minutes it will take her to run 10 miles, the number of minutes is our unknown with 10 in as miles and the ratio completed looks like this:
[tex]\frac{24}{3}=\frac{x}{10}[/tex]
Cross multiply to get 3x = 240 so
x = 80 minutes
