एक आदमी \(\frac{1}{x}\)किमी/घंटा की गति से यात्रा करता है और \(\rm \frac{1}{x^2}\) किमी/घंटा की गति से वापस आता है,
प्रयुक्त सूत्र:
औसत गति = \(\frac{2\times speed_1\times speed_2}{speed_1 + speed_2}\)
गणना:
औसत गति = \(\frac{2\times\frac{1}{x}\times\frac{1}{x^2}}{\frac{1}{x}+\frac{1}{x^2}}\)
⇒ \(\frac{\frac{2}{x^3}}{\frac{x + 1}{x^2}}\)
⇒ \(\rm \frac{2}{x+x^2}\)
∴ औसत गति \(\rm \frac{2}{x+x^2}\) है।
