Question
Download Solution PDFएक रेलगाड़ी 45 किमी/घंटा की औसत गति से अपने गंतव्य स्थान पर समय पर पहुँचती है। यदि यह 30 किमी/घंटा की औसत गति से चलती है, तो यह 15 मिनट देरी से पहुँचती है। कुल दूरी कितनी है?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिया गया है:
वास्तविक गति = 45 किमी/घंटा
घटी हुई गति = 30 किमी/घंटा
प्रयुक्त सूत्र:
कुल दूरी = \(\frac{(S_1 × S_2)}{S_1-S_2} \times (T_1+T_2)\)
यहाँ,
S1 = वास्तविक गति
S2 = घटी हुई गति
T1 = समय 1
T2 = समय 2
गणना:
अवधारणा के अनुसार,
कुल दूरी = \(\frac{(45 × 30)}{45-30} \times (0+\frac{1}{4})\)
⇒ \(\frac{(1350)}{15} \times \frac{1}{4}\)
⇒ 22.5 किमी
∴ A और B के बीच की दूरी 22.5 किमी है।
