Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
सुजाताचा वेग = 2.85 किमी/तास
अंजलीचा वेग = 1.5 मीटर/सेकंद
त्यांच्यातील अंतर = 693 मीटर
वापरलेली संकल्पना:
जेव्हा दोन व्यक्ती x किमी/तास आणि y किमी/तास विरुद्ध दिशेने प्रवास करतात तेव्हा सापेक्ष वेग (x + y) किमी/तास असतो.
वेळ = अंतर/वेग
गणना:
2.85 किमी/तास = 2.85 × (5/18)
⇒ 0.80 मीटर/सेकंद
सापेक्ष गती = 0.79 + 1.5 = 2.29 m/s
वेळ = अंतर/सापेक्ष गती
⇒ वेळ = 693/2.29
⇒ वेळ = 302.62 सेकंद
⇒ वेळ = 5.04 मिनिटे
5.04 मिनिटांनी ते पहिल्यांदा भेटतील.
