Download Solution PDFदिलेली माहिती:
प्रतिवाह प्रवास केलेले अंतर = अनुवाह प्रवास केलेले अंतर = 15 किमी = 18 किमी
प्रतिवाह प्रवास करण्यासाठी लागणारा वेळ = अनुवाह प्रवास करण्यासाठी लागणारा वेळ = 3 तास
संकल्पना किंवा सूत्र:
वर्तमानाचा वेग = (अनुवाह वेग - प्रतिवाह वेग) ÷ 2
गणना:
माणूस (m) आणि प्रवाह (c) च्या गतीची गणना करा
⇒ प्रतिवाह वेग = अंतर ÷ वेळ = 15 किमी ÷ 3 तास = 5 किमी/तास (m - c = 5 किमी/तास)
⇒ अनुवाह वेग = अंतर ÷ वेळ = 18 किमी ÷ 3 तास = 6 किमी/तास (m + c = 6 किमी/तास)
c साठी ही समीकरणे सोडवून:
⇒ c = (m + c - m + c) ÷ 2 = (6 किमी/तास - 5 किमी/तास) ÷ 2= \(\frac{1}{2}\) किमी/तास
म्हणून प्रवाहाचा वेग \(\frac{1}{2}\) किमी/तास आहे.
