Answer: Each person ran [tex]\dfrac{1}{32}~\textup{miles}.[/tex]
Step-by-step explanation: Given that a 2-person relay race is 1 over 16 miles long and each person runs the same length.
We are to find the distance ran by each person.
Let each person ran x miles.
Then, according to the given information, we have
[tex]x+x=\dfrac{1}{16}\\\\\\\Rightarrow 2x=\dfrac{1}{16}\\\\\\\Rightarrow x=\dfrac{1}{32}.[/tex]
Thus, each person ran [tex]\dfrac{1}{32}~\textup{miles}.[/tex]
