\n" );
document.write( "Hi
\n" );
document.write( "Let x and w represent the plane and wind speed respectively
\n" );
document.write( "Question states***
\n" );
document.write( " x + w = 240mph    |r = 240mi/1hr
\n" );
document.write( " x - w = 160mph    |r = 240mi/1.5hr
\n" );
document.write( "  2x = 400
\n" );
document.write( "   x = 200mph, the speed of the plane. tail Wind is 40mph  (240mph-200mph) \n" );
document.write( "

\n" );
