    क्यों तेरा सपना पूरा नहीं होता;
    हिम्मत वालों का इरादा नहीं अधूरा होता;
    जिस इंसान के होते हैं कर्म अच्छे;
    उस के जीवन में कभी अँधेरा नहीं होता।

    . शांत जल में एक नाव को अपने गंतव्य स्थान तक पहुंचने और वहां से अपने प्रारंभिक स्थान पर वापस आने में कुल 15 घंटे लगते हैं। उसी यात्रा के लिए नदी में प्रवाह होने पर 16 घंटे की आवश्यकता होती है। नाव और नदी की गति के बीच का अंतर 15 km/hr है। नदी के प्रवाह की गति ज्ञात कीजिए।
