Question
Download Solution PDFA और B, बिंदु P से बिंदु Q की ओर चलना प्रारंभ करते हैं। बिंदु P और बिंदु Q के बीच की दूरी 9 किमी है। B, A के 4 मिनट बाद चलना प्रारंभ करता है। A, बिंदु Q पर पहुँचने के तुरंत बाद, वापस लौटता है और एक किमी चलने के बाद B से मिलता है। यदि A, 10 मिनट में एक किमी चलता है, तो B की गति, किमी प्रति मिनट में कितनी होगी?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFA द्वारा तय की गई दूरी = 9 + 1 = 10 किमी
∴ A द्वारा लिया गया समय = 10 × 10 = 100 मिनट
∴ B द्वारा लिया गया समय = 100 - 4 = 96 मिनट
B द्वारा तय की गई दूरी = 9 - 1 = 8 किमी
∴ B की गति = 8/96 = 1/12 किमी प्रति मिनट
