Answer:
maximum value : y = - 1 at (2, -1)
No local minimum
Step-by-step explanation:
The function y=−x^2+4x−5. is a downward opening parabola.
The local maximum is at the vertex
y = - (xx - 4x ) - 5
y = - (xx - 4x +4 - 4) - 5
y = - (xx - 4x + 4) + 4 - 5
y = -(x - 2)^2 - 1
vertex at (2, -1)

For her first trip:
(1) +240.5+=+4d+%2B+450m+
For her 2nd trip:
(2) +146+=+3d+%2B+200m+
-------------------------
Multiply both sides of (1) by +3+
Multiply both sides of (2) by +4+,
Then subtract (2) from (1)
