Detailed Solution
Download Solution PDFदिया गया है:
यात्रा के पहले भाग के लिए गति = 40 किमी/घंटा
वापसी यात्रा के लिए गति = 60 किमी/घंटा
प्रयुक्त सूत्र:
औसत गति = (2 × गति1 × गति2) / (गति1 + गति2)
गणना:
औसत गति = (2 × 40 × 60) / (40 + 60)
⇒ औसत गति = (2 × 2400) / 100
⇒ औसत गति = 4800 / 100
⇒ औसत गति = 48 किमी/घंटा
∴ सही उत्तर विकल्प (2) है।
