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 ?

A
