The ques. is wrong. In same amount of time, distance travelled upstream should be less than distance travelled downstream.
\n" ); document.write( "So, Solving the ques, by reversing the data as upstream distance=29 miles and downstream distance =58 miles\r
\n" ); document.write( "\n" ); document.write( "Let boat's speed in still water = b,
\n" ); document.write( "Since time taken upstream = Time taken downstream
\n" ); document.write( "=> Distance upstream/ Net speed upstream = Distance downstream/net speed downstream
\n" ); document.write( "=> $\"29%2F%28b-4%29+=+58%2F%28b%2B4%29\"$
\n" ); document.write( "=> $\"b%2B4+=+2b-8\"$
\n" ); document.write( "=> $\"b=12\"$
\n" ); document.write( "So speed of boat in still water = 12 mph. \n" ); document.write( "

\n" );
