\n" ); document.write( "a plane traveled \"2835\" miles with the wind in 4.5 hours and \"2475\" miles against the wind in the same amount of time. find the speed of the wind.
\n" ); document.write( "

Let speeds, of plane in still air, and wind, be S and W, respectively
\n" );
document.write( "We then get: 
\n" );
document.write( "       Also, 
\n" );
document.write( "630 - W - W = 550 ------ Substituting 630 - W for S in eq (ii)
\n" );
document.write( "       - 2W = 550 - 630
\n" );
document.write( "       - 2W = - 80
\n" );
document.write( "Wind speed, or  \n" );
document.write( "

\n" );
