You can put this solution on YOUR website!
If x is the rate of the current, then:
\n" ); document.write( "6/20-x=10/20+x (being inversely proportional)
\n" ); document.write( "200-10x=120+6x
\n" ); document.write( "80=16x
\n" ); document.write( "x=5
\n" ); document.write( "The current is 5 mph. ☺☺☺☺
\n" ); document.write( "
\n" );
