Detailed Solution
Download Solution PDFदिया है:
n = 3
S1 = 25 किमी/घंटा
S2 = 40 किमी/घंटा
S3 = 50 किमी/घंटा
प्रयुक्त सूत्र:
यदि किसी दूरी को 'n' समान भागों में विभाजित किया जाए, जिनमें से प्रत्येक ने अलग-अलग गति से यात्रा की हो
औसत गति = \(\frac{n}{\frac{1}{S_1}+\frac{1}{S_2}+\frac{1}{S_3}+....+\frac{1}{S_n}}\)
जहाँ, n = समान भागों की संख्या
गणना:
औसत गति = \(\frac{3}{\frac{1}{25}+\frac{1}{40}+\frac{1}{50}}\)
⇒ औसत गति = \(\frac{3}{\frac{8}{200}+\frac{5}{200}+\frac{4}{200}}\)
⇒ औसत गति = 3 ÷ (17/200)
⇒ औसत गति = (3 × 200)/17 = 35.29 ≈ 35.3 किमी/घंटा
∴ पूरी यात्रा की औसत गति 35.3 किमी/घंटा है।
