\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1. Using the rate\r

\r\n" );
document.write( "    Then the problem is solved in two steps.\r\n" );
document.write( "\r\n" );
document.write( "    First, you find the rate; next, you find the required time.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    The rate is the distance divided by the time.   In your case, it is\r\n" );
document.write( "\r\n" );
document.write( "        rate =  = 27 miles per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    Then the required time is  the distance divided by the rate:\r\n" );
document.write( "\r\n" );
document.write( "        the required time =  = 8 hours.    ANSWER\r\n" );
