If a train runs with the speed of 52km/h, it reaches its destination late by 15 minutes. However, if its speed is 65km/h, it is late by 5 minutes only. The right time for the train to cover its journey is: यदि कोई ट्रेन 52 किमी/घंटा की चाल से चलती है, तो यह अपने गंतव्य स्थल पर 15 मिनट की देरी से पहुँचती है | लेकिन, जब इसकी चाल 65 किमी/घंटा होती है, तो यह केवल 5 मिनट देर करती है | ट्रेन को यात्रा पूर्ण करने में लगने वाला सही समय क्या है?
