Simran moved in her North-West direction for 2 km. From there, she turned 90° clockwise and moved 2 km again. She turned 90° clockwise and traveled 2 km. Now, what is her direction from the original position?

1. A

   Western Region

2. B

   North East Region

3. C

   South East Region

4. D

   South West Region

Appeared in: AIIMS Nagpur NO - 2018

Explanation

• The problem requires tracking movement and determining the final position relative to the starting point.
• The first move is North-West, followed by a 90° clockwise turn to North-East, and another 90° clockwise turn to South-East.
• A vector-based or coordinate-based calculation shows the final displacement from the origin is towards the North-East quadrant.
• The path consists of three 2 km segments: NW, then NE, then SE. The vector sum of these movements results in a final position that is to the North and East of the starting point.

Why Other Options Were Wrong

• Option A: A final position in the Western region would require a net negative displacement on the x-axis (a net westward movement), which did not occur.
• Option C: This is the direction of the last leg of the journey, not the final position relative to the starting point. The question asks for the direction from the original position, not the final direction of travel.
• Option D: A final position in the South-West region would require net negative displacements on both the x-axis (West) and y-axis (South). The net movement was actually positive on both axes.

Related Visual

• Visual 1: Diagram - A diagram showing a compass with the four cardinal (N, S, E, W) and four intermediate (NE, NW, SE, SW) directions. An arrow path should be overlaid, starting from the center, moving 2 units NW, then 2 units NE, then 2 units SE. A final dashed arrow from the start point to the end point would clearly show the North-East direction.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Direction and Distance Reasoning as background academic context rather than a clinical decision trigger.
• This question tests logical and spatial reasoning, a fundamental skill for problem-solving in any field, including nursing.
• In a clinical setting, spatial awareness is crucial for tasks like navigating a large hospital, locating emergency equipment quickly, or understanding anatomical diagrams and patient positioning.
• What if? - If Simran had turned 90° counter-clockwise for her first turn instead of clockwise, her path would have been NW -> SW -> SE. Her final position relative to the start would have been in the South-West region.

How to Approach the Question

• First, establish a starting point and a clear understanding of the cardinal (N, E, S, W) and intermediate (NE, NW, SE, SW) directions.
• Draw a simple diagram. Represent the starting point as an origin (0,0).
• Trace each step of the journey, paying close attention to the direction and the nature of the turn (clockwise/counter-clockwise) and the angle (90°).
• After plotting all movements, determine the final position relative to the starting point.
• Read the question carefully to distinguish between the final direction of travel and the final position relative to the start.
• Select the option that correctly describes the direction from the starting point to the final point.
