Analyzing Puja's Directional Movement
To find the shortest distance and direction from Puja's final stop (Point P) back to the starting point (Point A), we can track his movements using coordinates.
Let Point A be the origin, represented as \((0, 0)\) on a coordinate plane, where North is the positive y-axis and East is the positive x-axis.
Tracking Puja's Path
- Start at Point A: Position \((0, 0)\).
- Move 1: Drives 31 km South. New position is \((0, -31)\).
- Move 2: Turns left (now facing East) and drives 40 km. New position is \((0 + 40, -31) = (40, -31)\).
- Move 3: Turns left (now facing North) and drives 36 km. New position is \((40, -31 + 36) = (40, 5)\).
- Move 4: Turns left (now facing West) and drives 41 km. New position is \((40 - 41, 5) = (-1, 5)\).
- Move 5: Turns left (now facing South) and drives 5 km. New position is \((-1, 5 - 5) = (-1, 0)\).
- Stop at Point P: Final position is \((-1, 0)\).
Calculating Return Trip from P to A
Puja stops at Point P, located at coordinates \((-1, 0)\). He needs to return to Point A, located at \((0, 0)\).
The required displacement vector from P to A is calculated as:
\( \text{Displacement} = A - P = (0, 0) - (-1, 0) \) \( \text{Displacement} = (0 - (-1), 0 - 0) = (1, 0) \)The resulting displacement vector is \((1, 0)\). This indicates a movement of 1 km in the positive x-direction (East) and 0 km in the y-direction.
Conclusion
Therefore, to reach Point A again from Point P, Puja needs to drive 1 km to the east.
