\n" ); document.write( ".
\n" ); document.write( "as total for 5 days is 30,,
\n" ); document.write( ".
\n" ); document.write( "x +x+3 +x+6 +x+9 =x+12 =30
\n" ); document.write( ".
\n" ); document.write( "5x +30 =30
\n" ); document.write( ".
\n" ); document.write( "5x =0
\n" ); document.write( ".
\n" ); document.write( "x= 0,,,,,,,or he doesn't have to walk at all 1st day,,
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "check,,0+3+6+9+12 = 30,,,,ok
