\r\n" );
document.write( "Let t be the time to intercept, in hours.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the aircraft will cover the distance of 350*t kilometers,\r\n" );
document.write( "while the plane will cover 450*t kilometers.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The sum of these distances is 200 kilometers, which gives you an equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    350*t + 450*t = 200.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve for t :\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     800*t = 200\r\n" );
document.write( "\r\n" );
document.write( "     t =  =  of an hour = 15 minutes.    AMSWER\r\n" );
