Final answer:
The point P should be chosen at P = 0.50 units from A.
Step-by-step explanation:
To maximize the angle θ, we need to find the point P on line segment AB that is the farthest away from point A. This can be done by comparing the distances AP and PB and choosing the point P that is equidistant from both A and B. In this case, since AB is a line segment, point P should be chosen at the midpoint of AB, which is exactly between A and B.
Therefore, the point P should be chosen at P = 0.50 units from A.
