t, some time unit
\n" ); document.write( "Speed for A, \"8%2Ft\"
\n" ); document.write( "Speed for B, \"12%2Ft\"
\n" ); document.write( "x, the time for B to close the initial 84 feet distance from A.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%2812%2Ft-8%2Ft%29x=84\", again t is just a time unit; not a variable.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=84%2F4\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=21\" time units B to catchup to A.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Distance A traveled during the catchup time:
\n" ); document.write( "\"%288%29%2821%29=highlight%28168%29\"
\n" ); document.write( "
\n" );
