Let the distance covered be s units.
\n" ); document.write( "If both John and Henry meet after t min, then
\n" ); document.write( "s = (s/9)Xt + (s/6)Xt, s being the total distance.
\n" ); document.write( "=> 1 = t(1/9 + 1/6)
\n" ); document.write( "=> 1 = t(5/18)
\n" ); document.write( "=> t = 18/5 min
\n" ); document.write( "
\n" );
