In a steam running at 2 km/h, a motorboat goes 10 km upstream and back again to the starting point in 55 min. Find the speed of the motorboat in still water (A) 22 km/h (B) 32 km/h (c ) 42 km/h (D) 52 km/h

The speed of the current is 5 km/h. A motorboat goes 10 km upstream and back again to the starting point in 50 min. The speed, (in km/h) of the motorboat in still water is

A motorboat goes 24 km in 2 hour along the stream and 10 km in 1 hour against the stream. The speed of the motorboat in Kilometers per hour, is: एक मोटरबोट धारा के साथ 2 घंटे में 24 किमी और धारा के खिलाफ 1 घंटे में 10 किमी जाती है। प्रति घंटे किलोमीटर में मोटरबोट की गति है:

A boat can go 30 km downstream and 24 km upstream in 2 hours 27 minutes.Also, it can go 20km downstream and 8 km upstream in 74 minutes. What is the speed of the boat in still water in km/h? एक नाव 2 घंटे 27 मिनट में 30 किमी धारा के अनुकूल और 24 किमी धारा के प्रतिकूल जा सकती है | साथ ही, यह 74 मिनट में 20 किमी धारा के अनुकूल और 8 किमी धारा के प्रतिकूल जा सकती है | स्थिर जल में नाव की चाल ( किमी/घंटा में ) ज्ञात करें |
