A takes 6 hours more than B to cover a distance of 60 km. But if A doubles his speed, he takes 3 hours less than B to cover the same distance. The speed (in km/hr) of A is:

A takes 30 minutes more than B to cover a distance of 15 km at a certain speed. But if A doubles his speed, he takes one hour less than B to cover the same distance. What is the speed (in km/h) of B? A को एक निश्चित चाल से 15 किमी की दूरी तय करने में B से 30 मिनट अधिक लगते हैं | लेकिन यदि A अपनी चाल दोगुनी कर ले, तो उसे इसी दूरी को तय करने में B से एक घंटा कम लगेगा |B की चाल ( किमी/घंटा में ) ज्ञात करें |

A takes 2 hours more than B to cover a distance of 40km. If A doubles his speed he takes 1 1/2 hours more than B to cover 80 km. To cover a distance of 90 km, how much time will B take travelling at his speed? A को 40 किमी की दूरी तय करने में B से 2 घंटे अधिक लगते हैं। यदि A अपनी चाल को दोगुना कर देता है तो उसे 80 किमी की दूरी तय करने में B से 1 1/2 घंटे अधिक लगते हैं। 90 किमी की दूरी तय करने के लिए, B को अपनी चाल से यात्रा करने में कितना समय लगेगा ?
