3.5 hours for 33.25 miles is 9.5 mph
\n" ); document.write( "9.5 hours for 33.25 miles is 3.5 mph\r
\n" ); document.write( "\n" ); document.write( "x+y=9.5 mph
\n" ); document.write( "x-y=3.5 mph
\n" ); document.write( "2x=13 mph
\n" ); document.write( "x=6.5 mph speed in still water
\n" ); document.write( "y=3 mph current.
\n" ); document.write( "
\n" );
