Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
ध्रुव ओलांडण्याची वेळ = 5 सेकंद
बोगदा ओलांडण्यासाठी लागणारा वेळ = 20 सेकंद
वापरलेले सूत्र:
वेग = अंतर/वेळ
गणना:
बोगद्याची लांबी xमीटर आणि ट्रेनची लांबी yमीटर असू द्या
वेळ = अंतर/वेग
⇒ 5 = (y/90)
⇒ y = 450 मीटर
बोगदा ओलांडण्याची वेळ = अंतर/वेग
⇒ 20 = (y + x)/90
⇒ 20 × 90 = (450 + x)
⇒ x = 1800 - 450 = 1350
∴ बोगद्याची लांबी 1350 मीटर आहे.
