You can put this solution on YOUR website!
r, speed of plane without any wind
\n" ); document.write( "w, speed of wind
\n" ); document.write( "
\n" ); document.write( "

\r\n" );
document.write( "                     SPEED     TIME       DISTANCE\r\n" );
document.write( "\r\n" );
document.write( "WITH WIND            r+w       3           870\r\n" );
document.write( "\r\n" );
document.write( "AGAINST WIND         r-w      690/(r-w)    690\r\n" );
document.write( "

\n" ); document.write( "All you can find is that the actual speed traveling with the wind was 290 miles per hour. The wind speed cannot be found. \n" ); document.write( "

\n" );
