6R=1029
\n" ); document.write( "R=1029/6
\n" ); document.write( "R=171.5 SPEED AGAINST THE HEADWIND
\n" ); document.write( "1029/3.333=R
\n" ); document.write( "R=308.73 IS THE SPEED WITH THE HEADWIND
\n" ); document.write( "THE DIFFERENCE BETWEEN THESE TWO SPEEDS DIVIDED BY 2 IS THE HEADWIND
\n" ); document.write( "(308.73-171.5)/2=137.23/2=68.62 IS THE SPEED OF THE HEADWIND.
