Three hours difference, \"128-161=33\" miles change.
\n" ); document.write( "Find rate.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y=mx+b, and \"m=33%2F3=11\". Pick either point for b; (1,128) or (4,161).
\n" ); document.write( "You finish.
\n" ); document.write( "
\n" );
