A bike is chasing a car, which is 12 km ahead of it. The speeds of the bike and the car are 96 km/hr and 60 km/hr, respectively. If the bike catches the car in 'a' minute, then find the distance covered by the bike in (a - 16) hours.
312 km
384 km
360 km
398 km
Answer: B
Relative speed = 96 - 60 = 36 km/hr. Catching time = 12/36 hour = 20 minutes, so a = 20. Therefore, a - 16 = 4 hours. Distance covered by the bike = 96 × 4 = 384 km.
एक बाइक, एक कार का पीछा कर रही है, जो उससे 12 किमी आगे है। बाइक और कार की चाल क्रमशः 96 किमी/घंटा और 60 किमी/घंटा है। यदि बाइक, कार को 'a' मिनट में पकड़ लेती है, तो बाइक द्वारा (a - 16) घंटे में तय की गई दूरी ज्ञात कीजिए।
312 किमी
384 किमी
360 किमी
398 किमी
उत्तर: B
सापेक्ष चाल = 96 - 60 = 36 किमी/घंटा। पकड़ने में समय = 12/36 घंटा = 20 मिनट, इसलिए a = 20। अतः a - 16 = 4 घंटे। बाइक द्वारा तय दूरी = 96 × 4 = 384 किमी।
