d= 60 km
\n" ); document.write( "let paddling speed in still water be x km/h
\n" ); document.write( "with current speed = (x+6) km/h\r
\n" ); document.write( "\n" ); document.write( "t= 4 hours\r
\n" ); document.write( "\n" ); document.write( "D= r*t
\n" ); document.write( "160=(x+6)*4
\n" ); document.write( "divide by 4
\n" ); document.write( "40= x+6
\n" ); document.write( "subtract 6 from both sides
\n" ); document.write( "34=x\r
\n" ); document.write( "\n" ); document.write( "34 km/h in still water
\n" ); document.write( "
\n" ); document.write( "
