Look at the faces of the searchers. You can tell how serious they are about their mission.
From the looks of the terrain and road net work, I can understand their determined looks. The terrain is very mountaneous and paved roads to the south seem to be three miles away. To the west, they seem closer to between five and six. There is a closer road to the north east, but she would need to be moving in that direction.
A physically fit individual accustomed to hiking would probably be able to read the terrain and then steadily walk out cross country to lower ground and a paved road. Likewise, a physically fit person not accustomed to hiking could do it as well, though probably not as efficiently. What worries me is that the lost person does not seem to be an experienced hiker and may also not have a good level of physical fitness. Needless to say, mountainous terrain can be difficult to follow a set direction due to steep terrain or getting disoriented. This can lead to retracing steps and exhaustion.
I have also seen a psychological mental impact in hiking when an individual is not accustomed to being physically uncomfortable through say hiking, sports, out door work or the military. They seem to get mentally
exhausted when they are only physically tired (not exhausted) and just
moderately uncomfortable. The mental exhaustion then quickly compounds and worsen the physical situation to the point where the person gets confused and physically exhausted.
In short, we need to hope she is found fast.
