From an entrance, a person walks 28 meters left, then turns right and walks 13 meters. They turn right again and walk 12 meters, and then walk 16 meters further in the same direction. What is the total distance covered in the last straight path?

1. A

   16 meters

2. B

   28 meters

3. C

   12 meters

4. D

   40 meters

Appeared in: KGMU 2023

Explanation

• The question specifically asks for the total distance of the 'last straight path'.
• This path begins after the second right turn and consists of two consecutive movements in the same direction.
• The total distance is calculated by adding the lengths of these two segments: 12 meters + 16 meters = 28 meters.

Why Other Options Were Wrong

• Option A: This value represents only the second part of the final straight path, not the entire length.
• Option C: This value represents only the first part of the final straight path.
• Option D: This is an incorrect sum and does not represent any logical combination of the movements described for the final path.

Related Visual

• Visual 1: Diagram - A top-down diagram illustrating the person's path with arrows and labels for each segment's distance (28m, 13m, 12m, 16m). This would visually clarify that the last two segments form a single straight line.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Direction and Distance as background academic context rather than a clinical decision trigger.
• This is a logical reasoning question designed to assess problem-solving skills and attention to detail, which are essential attributes for nurses.
• While not a clinical scenario, the ability to accurately interpret and follow sequential instructions is crucial in executing multi-step medical protocols, administering medications, and providing patient care.
• What if the question asked for the total distance walked? The answer would be the sum of all movements: 28 + 13 + 12 + 16 = 69 meters.

How to Approach the Question

• First, read the question carefully to identify exactly what is being asked. Here, the key phrase is 'total distance covered in the last straight path'.
• Break down the person's movement into a sequence of steps, noting each change in direction and the distance covered.
• Isolate the specific part of the journey that corresponds to the 'last straight path'. Notice that it's composed of two parts: a 12-meter walk and a 16-meter walk 'in the same direction'.
• Since the two movements are in the same direction, add their distances together to find the total length of that straight path.
• Compare your calculated result with the given options to find the correct answer.
