दौड़ने का समय = [10 घंटे के लिए प्रत्येक 1 घंटा]
गति = [10, 9, 8, 7, 6, 5, 4, 3, 2, 1] किमी/घंटा
प्रयुक्त अवधारणा:
औसत गति = कुल दूरी/कुल समय
गणना:
⇒ कुल समय = 10 घंटे
⇒ कुल दूरी = प्रत्येक घंटे में दूरियों का योग
= प्रत्येक घंटे के लिए (गति × समय) का योग
= 10 × 1 + 9 × 1 + ... + 1 × 1 = 55 किमी
⇒ औसत गति = 55 किमी/10 घंटे = 5.5 किमी/घंटा
इसलिए, R की औसत गति 5.5 किमी/घंटा है।
