ऋषि 198 किमी की दूरी 66 किमी/घंटा की गति से, अगली 584 किमी दूरी 73 किमी/घंटा की गति से और अगली 656 किमी दूरी 82 किमी/घंटा की गति से तय करता है।
पूरी यात्रा के लिए उसकी औसत गति (किमी/घंटा में) ज्ञात कीजिए। (उत्तर को दशमलव के दो स्थान तक पूर्णांकित करें।)
Detailed Solution & Logic
75.68
Total distance:
$198 + 584 + 656 = 1438$ km
Time taken:
$198 \div 66 = 3$ hr
$584 \div 73 = 8$ hr
$656 \div 82 = 8$ hr
Total time:
$3 + 8 + 8 = 19$ hr
Average speed:
$= \frac{1438}{19} = 75.68$ km/hr
Correct Answer: 75.68 km/hr
