A man can row 8km/h in still water and he finds that it takes him twice as long to row up as to row down the stream. What is the rate of the stream. |

Answer» Step-by-step explanation: Let RATE of the stream =x km /h UPSTREAM speed of boat=(8-×) km/hr downstream speed of boat=(8+×) km/hr let distance =D km Time taken upstream =D/(8-×) Time taken downstream =D/(8+×) D/(8-×)=2D/(8+×) (8+×)=2(8-×) (8+×)=16-2x x+2x=16-8 3x=8 x=2.67km/hr If it helps please mark me in BRAINLEIST...
