For this case we propose a system of equations:
x: Let the variable representing the number of miles Asanji ran
y: Let the variable representing the number of miles Kathryn ran
According to the statement data we have:
![y-26.9 = x\\x = 11.1](https://img.qammunity.org/2020/formulas/mathematics/middle-school/i24f4gcxasqxfyqhfad6vr3fb4j7qj6q7d.png)
Substituting the second equation into the first we have:
![y-26.9 = 11.1\\y = 11.1 + 26.9\\y = 38](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xtmzqkv621si06a7tc1zzkbmkw74z7burl.png)
So, we have Karhryn ran 38 miles.
Answer:
Karhryn ran 38 miles.
