alleryएक ट्राम किसी मार्ग की एक-तिहाई दूरी 20 km/h की चाल से और शेष दो-तिहाई दूरी 40 km/h की चाल से तय करती है। इसकी औसत चाल क्या है?
A30 km/h
B35 km/h
C28 km/h
D32 km/h
Answer & Solution
Correct answer: A. 30 km/h
60 km के मार्ग के लिए, 20 km की दूरी तय करने में 1 घंटा और 40 km में 1 घंटा लगता है, जिससे औसत चाल 60 / 2 = 30 km/h प्राप्त होती है।
