You can put this solution on YOUR website!
p = the speed of the plane in still air
\n" ); document.write( "w = the speed of the wind
\n" ); document.write( "p + w = 3k / 5
\n" ); document.write( "p - w = 3k/6
\n" ); document.write( "add them
\n" ); document.write( "2p = (15K + 18K) / 30
\n" ); document.write( "2p = 33k / 30
\n" ); document.write( "p = 11k / 20
\n" ); document.write( "p = .55K
\n" ); document.write( "p = 550 mi/hr answer
\n" ); document.write( "p + w = 3k / 5
\n" ); document.write( "550 + w = 3K / 5
\n" ); document.write( "w = 600 - 550
\n" ); document.write( "w = 50 mi/hr
\n" ); document.write( "check
\n" ); document.write( "p - w = 3k/6
\n" ); document.write( "550 - 50 = 500
\n" ); document.write( "500 = 500
\n" ); document.write( "OK \n" ); document.write( "

\n" );
