Two cyclists cover the same distance at 15 km/hr and 16 km/hr, respectively. If one cyclist takes 16 minutes longer than the other, then the distance travelled by each cyclist is:दो साइकिल चालक समान दूरी क्रमशः 15 किमी/घंटा और 16 किमी/घंटा की चाल से तय करते हैं। यदि एक साइकिल चालक दूसरे से 16 मिनट अधिक समय लेता है, तो प्रत्येक साइकिल चालक द्वारा तय की गई दूरी कितनी है?

Correct answer: A. 64 km64 किमी
Explanation
d/15 − d/16 = 16/60 hr. So d/240 = 4/15, giving d = 240 × 4/15 = 64 km. (Check: 64/15 h = 256 min, 64/16 h = 240 min, difference 16 min.)d/15 − d/16 = 16/60 घंटा। अतः d/240 = 4/15, जिससे d = 240 × 4/15 = 64 किमी। (जाँच: 64/15 घंटा = 256 मिनट, 64/16 घंटा = 240 मिनट, अंतर 16 मिनट।)More Mathematical Reasoning and Aptitude questions
