Quantity I : The distance travelled by a bus in 4 hours is 320 km. If the speed of bus is increased by 20% then what will be the time taken by bus to cover the triple of distance? Quantity II: A bus which is travelling from point A to point B which are 150 km apart, covers half of distance with 25 km/h and rest of distance with 30 km/hr and take break of 30 minutes after travelling half of distance then what will be the total time taken by bus to reach destination? मात्रा I: 4 घंटे में एक बस द्वारा तय की गई दूरी 320 किमी है। यदि बस की गति में 20% की वृद्धि हुई है, तो दूरी के तिगुने भाग को तय करने के लिए बस द्वारा लिया गया समय क्या होगा? मात्रा II: एक बस जो बिंदु A से बिंदु B तक यात्रा कर रही है जो कि 150 किमी की दूरी पर है, 25 किमी / घंटा के साथ आधी दूरी तय करती है और 30 किमी / घंटा के साथ बाकी दूरी तय करती है और आधी दूरी की यात्रा करने के बाद 30 मिनट का विराम लेती है। गंतव्य तक पहुंचने के लिए बस द्वारा लिया गया कुल समय क्या होगा?
