Detailed Solution
Mapping Jessica's Journey
We can track Jessica's movement using a coordinate system where Point A is the origin (0,0). North is the positive y-axis, East is the positive x-axis.
- Start at A: (0, 0)
- Move 1 (North 56 km): Position becomes (0, 56).
- Move 2 (Right turn -> East 58 km): Position becomes (0 + 58, 56) = (58, 56).
- Move 3 (Right turn -> South 61 km): Position becomes (58, 56 - 61) = (58, -5).
- Move 4 (Right turn -> West 61 km): Position becomes (58 - 61, -5) = (-3, -5).
- Move 5 (Right turn -> North 5 km): Final position P becomes (-3, -5 + 5) = (-3, 0).
Calculating Return Path from P to A
The final location is Point P at (-3, 0). The starting Point A is at (0, 0).
To find the shortest distance and direction from P to A:
- East-West Displacement: The difference in the x-coordinates is \(0 - (-3) = 3\).
- North-South Displacement: The difference in the y-coordinates is \(0 - 0 = 0\).
The net displacement is 3 km along the positive x-axis. This corresponds to moving 3 km towards the East.
Therefore, Jessica needs to drive 3 km to the East from Point P to reach Point A.
