Let Gloria's speed = $\"s\"$
\n" ); document.write( "Then Stacey's speed will be $\"3s\"$
\n" ); document.write( "If they are going in opposite directions,
\n" ); document.write( "just add their speeds
\n" ); document.write( "given:
\n" ); document.write( " $\"t+=+5\"$ hrs
\n" ); document.write( " $\"d+=+420\"$ mi
\n" ); document.write( " $\"420+=+%28s+%2B+3s%29%2A5\"$
\n" ); document.write( " $\"420+=+20s\"$
\n" ); document.write( " $\"s+=+21\"$ mi/hr
\n" ); document.write( "and
\n" ); document.write( " $\"3s+=+3%2A21\"$
\n" ); document.write( " $\"3s+=+63\"$ mi/hr
\n" ); document.write( "Stacey's speed is 63 mi/hr and
\n" ); document.write( "Gloria's speed is 21 mi/hr
\n" ); document.write( "check:
\n" ); document.write( " $\"s+%2B+3s+=+21+%2B+63\"$
\n" ); document.write( " $\"s+%2B+3s+=+84\"$
\n" ); document.write( " $\"420+=+84%2A5\"$
\n" ); document.write( " $\"420+=+420\"$
\n" ); document.write( "OK\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
