3000/6.25=480 PLANE SPEED AGAINST THE WIND
\n" ); document.write( "3000/5=600 PLANE SPEED WITH THE WIND
\n" ); document.write( "(600-480)/2=120/2=60 MPH FOR THE WIND
\n" ); document.write( "PROOF:
\n" ); document.write( "600-60=480+60
\n" ); document.write( "540=540 SPEED FO THE PLANE IN STILL AIR.\r
