Detailed Solution
Download Solution PDFदिया गया है:
पुलिसकर्मी और चोर के बीच की दूरी = 600 m
पुलिसकर्मी की गति = 9 km/h
चोर की गति= 8 km/h
प्रयुक्त सूत्र:
दूरी = सापेक्ष गति × समय
गणना:
दूरी = सापेक्ष गति × समय
⇒ 600 = (9 - 8) × (5/18) × समय
⇒ समय = (600 × 18)/5 = 120 × 18
⇒ समय = 2160 sec = (2160/3600) घंटे
पुलिसकर्मी द्वारा तय की गई दूरी = 9 × (2160/3600)
⇒ (9 × 3)/5 = 5.4 km
∴ सही उत्तर 5.4 km है।
