Detailed Solution
Download Solution PDF∵ ट्रेन और साइकिल चालक समान दिशा में चल रहे हैं,
सापेक्ष गति = 84 – 12 = 72 किमी/घंटे = 72 × 5/18 = 20 मीटर/सेकंड
अब, साइकिल चालक को पार करने में लगने वाला समय = ट्रेन की लम्बाई/ सापेक्ष गति
⇒ 13.5 = ट्रेन की लम्बाई /20
∴ ट्रेन की लम्बाई = 20 × 13.5 = 270 मीटर
