Mohit runs round a square field, of side \( 60 \mathrm{~m}, 8 \) times. What distance does he cover? Gagan runs around a rectangular field of length 160 m and breadth \( 85 \mathrm{~m}, 6 \) times. What distance does Gagan cover? Who covers more distance and by how much?

Answer

मोहीत ने 1920 मीटर और गगन ने 2940 मीटर तय किया। गगन ने मोहीत से 1020 मीटर अधिक दूरी तय की है।

Solution

मोहीत और गगन द्वारा तय की गई दूरी की गणना निम्नलिखित है: ### 1. मोहीत द्वारा तय की गई दूरी: - **क्षेत्र का आकार:** वर्ग (चौड़ाई = 60 मीटर) - **वर्ग की परिधि:** \( 4 \times 60 = 240 \) मीटर - **दौड़ने की संख्या:** 8 बार - **कुल दूरी:** \( 240 \times 8 = 1920 \) मीटर ### 2. गगन द्वारा तय की गई दूरी: - **क्षेत्र का आकार:** आयत (लंबाई = 160 मीटर, चौड़ाई = 85 मीटर) - **आयत की परिधि:** \( 2 \times (160 + 85) = 2 \times 245 = 490 \) मीटर - **दौड़ने की संख्या:** 6 बार - **कुल दूरी:** \( 490 \times 6 = 2940 \) मीटर ### 3. तुलना और अंतर: - **मोहीत की कुल दूरी:** 1920 मीटर - **गगन की कुल दूरी:** 2940 मीटर - **अंतर:** \( 2940 - 1920 = 1020 \) मीटर **निष्कर्ष:** गगन ने मोहीत की तुलना में 1020 मीटर अधिक दूरी तय की है।

The Deep Dive

Mohit runs around a square field, and the perimeter of a square is calculated as \(4 \times \text{side}\). So, the perimeter of Mohit's field is \(4 \times 60 \, m = 240 \, m\). Since he runs around it 8 times, he covers a total distance of \(240 \, m \times 8 = 1920 \, m\). For Gagan, the perimeter of the rectangular field is calculated as \(2 \times (\text{length} + \text{breadth})\). This gives us \(2 \times (160 \, m + 85 \, m) = 490 \, m\). If Gagan runs around this field 6 times, the total distance becomes \(490 \, m \times 6 = 2940 \, m\). Comparing the two distances, Gagan covers \(2940 \, m - 1920 \, m = 1020 \, m\) more than Mohit. So, Gagan takes the trophy here! 🏆
