Download Solution PDFधारा के प्रतिकूल 144 किमी की दूरी को तय करने में एक नाविक को 12 घंटे लगते हैं जबकि धारा के अनुकूल समान दूरी को तय करने में उसे केवल 9 घंटे लगते हैं। धारा की गति कितनी है?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिया गया है:
कुल दूरी = 144 किमी
नाविक द्वारा धारा के प्रतिकूल जाने में लिया गया समय = 12 घंटे
नाविक द्वारा धारा के अनुकूल जाने में लिया गया समय = 9 घंटे
प्रयुक्त अवधारणा:
धारा के प्रतिकूल गति = (U - V)
धारा के अनुकूल गति = (U + V)
धारा की गति = (अनुकूल गति - प्रतिकूल गति)/2
गति = दूरी/समय
गणना:
नाविक की धारा के प्रतिकूल गति = (U - V) = 144/12 = 12 किमी/घंटा
नाविक की धारा के अनुकूल गति = (U + V) = 144/9 = 16 किमी/घंटा
धारा की गति = (16 - 12)/2 = 4/2 = 2 किमी/घंटा
∴ सही उत्तर 2 किमी/घंटा है।
