Download Solution PDFदिलेले:
A आणि B एकाच बिंदूपासून 10 मी/से आणि 16 मी/से वेगाने गोलाकार मार्गावर (लांबी 400 मीटर) धावू लागतात.
वापरलेले सूत्र:
वेळ = \(\dfrac{distance}{speed}\)
गणना:
A ला एक फेरी पूर्ण करण्यासाठी लागणारा वेळ = 400/10 = 40 सेकंद
B ला एक फेरी पूर्ण करण्यासाठी लागणारा वेळ = 400/16 = 25 सेकंद
दोन्ही सुरुवातीच्या बिंदूवर भेटतील = 40, 25 चा लसावि
आवश्यक वेळ = लसावि = 5 × 5 × 8 = 200 सेकंद
∴ उत्तर 200 सेकंद आहे.
