समय = 5 घंटे
गति = 50 किमी/घंटा
प्रयुक्त सूत्र
गति = दूरी/समय
गणना
दूरी = 50 × 5 = 250 किमी
दूसरे अंतराल में:
दूरी = 250 + 250 × 120/100 = 300 किमी
गति = 50 + 50 × 120/100 = 60 किमी/घंटा
समय = 300/60 = 5 घंटे
तीसरे अंतराल में:
दूरी = 300 + 300 × 110/100 = 330 किमी
गति = (60 + 50)/2 = 55 किमी/घंटा
समय = 330/55 = 6 घंटे
कुल समय = 5 + 5 + 6 = 16 घंटे
उत्तर 16 घंटे है।
