Total track length \(= 3\) miles
Probability of the car within a half-mile of the sign indicating \(2\frac{1}{2}\) miles
So the car must be between the sign indicators showing \(2 - 3\) miles
So it must be in \(1\) mile portion of the total \(3\) miles track.
The probability \(= \frac{1}{3}\)
Answer C
