document.write( "According to the problem's context, Phil paddles upstream, while the log is floating toward him, i.e. downstream.\r\n" );
document.write( "\r\n" );
document.write( "The Phil effective rate relative the river's banks is 8-2 = 6 miles per hour.\r\n" );
document.write( "\r\n" );
document.write( "The log floats toward Phil with the rate 2 miles per hour, so their approaching rate is 6+2 = 8 miles per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the time when Phil will reach the log is  \"4%2F8\" = \"1%2F2\" of an hour, or 30 minutes.   ANSWER\r\n" );
