A boat takes 4 hours to go 44 Km downstream and it can go 20 km upstream in the same time. Find the speed of the stream and that of the boat in still water .प्र.१)एका नावेला 44 कि.मी. वेगाने प्रवाहाच्या दिशेने जाण्यासाठी ४ तास लागतात आणि त्याच वेळी प्रवाहाच्या विरुद्ध दिशेने 20 कि.मी. पर्यंत जाते तर नावेचा संथ पाण्यातील वेग व प्रवाहाचा वेग किती ? *

(1) प्रवाहाचा वेग(y)/Speed of the stream (y) =3km /hr ; नावेचा संथ पाण्यातील वेग/ Speed of the boat in still water (x)= 8km /hr

(2) प्रवाहाचा वेग(y)/Speed of the stream (y)=8km /hr ; नावेचा संथ पाण्यातील वेग (x) /Speed of the boat in still water (x)= 3km /hr

(3) प्रवाहाचा वेग(y)/Speed of the stream (y) =5km /hr ; नावेचा संथ पाण्यातील वेग (x) / Speed of the boat in still water (x)= 9km /hr

(4) प्रवाहाचा वेग(y)/Speed of the stream (y) = 5km /hr ; नावेचा संथ पाण्यातील वेग (x) /Speed of the boat in still water (x)= 8km /hr​
