To find the length of route 32, we can set up an equation using the information given. Let \( r \) represent the length of route 32.
According to the problem, Highway 199 is 85.3 miles long and is 7.2 miles longer than route 32.
We can express this relationship in the following equation:
\[
r + 7.2 = 85.3
\]
Now, we'll solve for \( r \):
\[
r = 85.3 - 7.2
\]
\[
r = 78.1
\]
Thus, the length of route 32 is \( 78.1 \) miles.
So the correct answer is **A) 78.1 miles**.
