\n" ); document.write( "

Let speed of current be C\r\n" );
document.write( "Then overall upstream and downstream speeds are 46 - C, and 46 + C, respectively \r\n" );
document.write( "We then get the following DISTANCE equation:  \r\n" );
document.write( "                                               12(46 - C) = 11(46 + C) ------ Denominators are equal and so are the numerators\r\n" );
document.write( "                                             12(46) - 12C = 11(46) + 11C\r\n" );
