A boat takes 80 minutes to 12 km upstream and 60 minutes to row 15 km downstream. How long will it take to row a distance of 36 km in still water? किसी नाव को धारा के प्रतिकूल 12 किमी जाने में 80 मिनट लगते हैं तथा धारा के अनुकूल 15 किमी जाने में 60 मिनट लगते हैं | स्थिर जल में इसे 36 किमी की दूरी तय करने में कितना समय लगेगा ?

A boat goes a distance of 4 km upstream in 2 hours and the same distance downstream in 20 minutes. How long will it take to go 10 1/2 km in still water? एक नाव 2 घंटे में 4 किमी धारा के प्रतिकूल जाती है और धारा के अनुकूल इतनी ही दूरी 20 मिनट में तय करती है | स्थिर जल में 10 1/2 किमी तक जाने में इसे कितना समय लगेगा ?

A boat covers 64 km upstream in 8 hours and 120 km downstream in 12 hours. What is the speed (in m/s) of the boat in still water? एक नाव धारा के प्रतिकूल 8 घंटे में 64 किमी तथा धारा के अनुकूल 12 घंटे में 1210 किमी की दूरी तय कर सकती है | स्थिर जल में नाव की चाल ( मीटर/सेकंड में ) क्या होगी ?

A boat covered a distance of 15 km upstream in 5 hours and a distance of 42 km downstream in 6 hours. The speed of the stream in km/h is: एक नाव धारा के विपरीत 15 किमी की दूरी 5 घंटे में और धारा के साथ 42 किमी, 6 घंटे में दुरी तय किया। किमी / घंटा में धारा की गति है:

A person can row a distance of 4 km upstream in 1 hour 20 minutes and can row back to the starting point in just 24 minutes. How much time (in hours) will he take to row 13 km in still water? / एक व्यक्ति धारा के विपरीत 4 किमी की दूरी 1 घंटा 20 मिनट में तय कर सकता है और अपने आरंभिक बिंदु तक केवल 24 मिनट में वापस पहुँच सकता है | स्थिर जल में 13 किमी की दूरी तय करने में उसे कितना वक्त (घंटे में) लगेगा ?

The time taken by a boat to travel 13 km downstream is the same as time taken by it to travel 7km upstream. If the speed of the stream is 3km/h, then how much time(in hours) will it take to travel a distance of 44.8 km in still water? / धारा के अनुकूल 13 किमी की दूरी तय करने में एक नाव को लगने वाला समय धारा के प्रतिकूल 7 किमी की दूरी तय करने में इसे लगने वाले समय के बराबर है | यदि धारा की चाल 3 किमी/घंटा है, तो स्थिर जल में इसे 44.8 किमी की दूरी तय करने में कितना समय ( घंटे में ) लगेगा ?
