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।
