An airplane travels 6282 kilometers against the wind in 9 hours and 7992 kilometers with the wind in the same amount of time. What is the rate of the plane in
\n" ); document.write( "stillair and what is the rate of the wind?
\n" ); document.write( "

Let plane's and wind's speeds, be S and W, respectively\r\n" );
document.write( "We then get the following: \r\n" );
document.write( "                                                  2S = 1,586 ----- Adding eqs (i) & (ii)\r\n" );
document.write( "                               Speed of plane, or \r\n" );
document.write( "\r\n" );
document.write( "                                             793 + W = 888 ----- Substituting 793 for S in eq (ii)\r\n" );
document.write( "\r\n" );
document.write( "                                Speed of wind, or
