Answer:
This really needs more information to answer correctly. What is bria's movement relative to the bus stop? Is she moving towards it, away, or to the side?
Step-by-step explanation:
Lacking this information, I can only say that as Bria's distance increases as she moves away from the bus stop (an assumption of direction). Let's say the bus stop is x yards distant in the other direction. Bria's distance from the bus stop varies from x+80 yards to x+190 yards. The signs would change if she were moving towards the bus stop. And they'd be something entirely different if a different angle were involved.
