A man is rowing a boat in a stream. As he passes under a bridge, a bottle of vodka falls into the water. Since it's 1/2 full, it floats. Since it's 1/2 empty, he doesn't hear it. 20 minutes later, he looks for the bottle to take another drink. He realizes it fell in the water. He turns around and rows back to the bottle, which is 1 mile from the bridge.
\n" ); document.write( "What is the speed of the stream?
\n" ); document.write( "=================================
\n" ); document.write( "The boat and the bottle are moving in the same medium.
\n" ); document.write( "He rows 20 mins away from it, so it takes 20 minutes to get back to it.
\n" ); document.write( "Doesn't matter if he is rowing upstream or down.
\n" ); document.write( "The bottle moves 1 mile in 40 minutes.
\n" ); document.write( "---> speed of the stream is 1.5 mi/hr
\n" ); document.write( "=============================
\n" ); document.write( "I did this problem some months or years ago.
\n" ); document.write( "Edwin also did it using a different method.
\n" ); document.write( "It's 1.5 mi/hr
\n" ); document.write( "------------
\n" ); document.write( "PS \"3 times faster\" is not 3 times as fast.
\n" ); document.write( " \n" ); document.write( "
\n" );
