Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
एकूण ट्रॅक लांबी = 1200 मीटर
A चा वेग = 2 मीटर/सेकंद ; B चा वेग = 4 मीटर/सेकंद
C चा वेग = 6 मीटर/सेकंद
वापरलेले सूत्र:
अंतर = सापेक्ष गती × वेळ
गणना:
A आणि B चा सापेक्ष वेग = (4 - 2) = 2 मीटर/सेकंद
B आणि C चा सापेक्ष वेग = (6 + 4) = 10 मीटर/सेकंद
A आणि C चा सापेक्ष वेग = (6 + 2) = 8 मीटर/सेकंद
A आणि B ने घेतलेला वेळ = 1200/2 = 600 सेकंद
B आणि C ने घेतलेला वेळ = 1200/10 = 120 सेकंद
A आणि C ने घेतलेला वेळ = 1200/8 = 150 सेकंद
A, B आणि C येथे भेटतील = ल.सा.वि. {600,120, 150} = 600 sec = 600/60 = 10 मिनिटे
∴ योग्य उत्तर 10 मिनिटे आहे.
