\n" ); document.write( "

Let total distance be D
\n" );
document.write( "based on the info., we get: 
\n" );
document.write( "
\n" );
document.write( "2D + 96 + 3D + 72 = 8D ------- Multiplying by LCD, 8
\n" );
document.write( "2D + 3D + 168 = 8D
\n" );
document.write( "5D - 8D = - 168
\n" );
document.write( "- 3D = - 168
\n" );
document.write( "D, or distance =  =  \n" );
document.write( "

\n" );
