Let $\"+s+\"$ = the speed of the jet in still air
\n" ); document.write( "Let $\"+w+\"$ = the speed of the wind
\n" ); document.write( " $\"+s+-+w+\"$ = the speed of the jet traveling against the wind
\n" ); document.write( " $\"+s+%2B+w+\"$ = the speed of the jet traveling with the wind
\n" ); document.write( "----------------------------------------------------
\n" ); document.write( "(1) $\"+3285+=+%28+s+-+w+%29%2A5+\"$
\n" ); document.write( "(2) $\"+3735+=+%28+s+%2B+w+%29%2A5+\"$
\n" ); document.write( "------------------------

\n" ); document.write( "(2) $\"+w+=+747+-+702+\"$
\n" ); document.write( "(2) $\"+w+=+45+\"$
