Answer:
Becky ran farther by 560 ft
Explanation:
Given that;
Keith's treadmill said he had run 10,000 feet
[tex]K=10,000\text{ ft}[/tex]Becky's treadmill said she had run two miles;
[tex]B=2\text{ miles}[/tex]converting miles to feet;
[tex]1\text{ mile = 5280 ft}[/tex]So;
[tex]\begin{gathered} B=2\text{ miles =2(5280) ft} \\ B=10,560\text{ ft} \end{gathered}[/tex]From the derived values, since B is greater than K, then Becky ran farther than Keith.
And by;
[tex]\begin{gathered} B-K=10,560-10,000 \\ =560\text{ ft} \end{gathered}[/tex]Therefore, Becky ran farther by 560 ft
