Let still water paddle speed : x km\r
\n" ); document.write( "\n" ); document.write( "Since stream current is 2 km per hour, therefore
\n" ); document.write( "upstream speed = x-2 and downstream speed = x+2\r
\n" ); document.write( "\n" ); document.write( "Time taken : distance/speed\r
\n" ); document.write( "\n" ); document.write( "Upstream : 24/(x-2)
\n" ); document.write( "Downstream : 24/(x+2)\r
\n" ); document.write( "\n" ); document.write( "The problem states that it takes three hours less time to paddle same distance downstream than same distance upstream.\r
\n" ); document.write( "\n" ); document.write( "Accordingly\r
\n" ); document.write( "\n" ); document.write( "24/(x-2) - 24/(x+2)=3\r
\n" ); document.write( "\n" ); document.write( "Solving above for x results in x=6\r
\n" ); document.write( "\n" ); document.write( "Ans : still water paddle speed : 6 km\r
