Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेले आहे:
एकूण अंतर = 144 किमी
प्रवाहाविरुद्ध जाण्यासाठी नावाड्याला लागणारा वेळ = 12 तास
प्रवाहाच्या दिशेने जाण्यासाठी नावाड्याला लागणारा वेळ = 9 तास
वापरलेली संकल्पना:
प्रवाहाविरुद्ध वेग = (U - V)
प्रवाहाच्या दिशेने वेग = (U + V)
वेग = अंतर/वेळ
गणना:
नावाड्याचा प्रवाहाविरुद्ध वेग = (U - V) = 144/12 = 12 किमी/तास
नावाड्याचा प्रवाहाच्या दिशेने वेग = (U + V) = 144/9 = 16 किमी/तास
प्रवाहाचा वेग = (16 - 12)/2 = 4/2 = 2 किमी/तास
∴ योग्य उत्तर 2 किमी/तास आहे.
