X आणि Y एकाच बिंदूपासून आणि एकाच वेळी 54 किमी/तास आणि 63 किमी/ताशी वेगाने सुरू होतात.
अंतर = 4225 मीटर
वापरलेले सूत्र:
अंतर = सापेक्ष वेग x वेळ
गणना:
विरुद्ध दिशेने दोन्हीचा सापेक्ष वेग = S2 + S1
= 54 + 63 = 117 किमी/तास = 117 * (5/18) = 65/2 मीटर/सेकंद.
तर,
विरुद्ध दिशेने धावताना मार्गावर प्रथमच भेटण्यासाठी त्यांना वेळ लागतो = मार्गाची लांबी / विरुद्ध दिशेने सापेक्ष वेग
= 4225/(65/2) = 130 सेकंद
म्हणून, आवश्यक वेळ 130 सेकंद आहे.
