Let the speed of the stream be x km/hr
Let the speed of the stream be x km/hrThen speed downstream = (10 + x) km/hr
Let the speed of the stream be x km/hrThen speed downstream = (10 + x) km/hrSpeed upstream
Let the speed of the stream be x km/hrThen speed downstream = (10 + x) km/hrSpeed upstream = (10−x)km/hr∴26(10+x)=14(10−x)⇒260−26x=140+14x⇒40x=120⇒x=3km/hr
