\n" ); document.write( "240=(R-W)3 AGAINST THE WIND.
\n" ); document.write( "R-W=240/3
\n" ); document.write( "R-W=80
\n" ); document.write( "240=(R+W)2 WITH THE WIND.
\n" ); document.write( "R+W=240/2
\n" ); document.write( "R+W=120
\n" ); document.write( "R-W=80
\n" ); document.write( "(120-80)/2=40/2=20 MPH FOR THE WIND SPEED.
\n" ); document.write( "PROOF:
\n" ); document.write( "240=80*3
