\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Let d be the one way distance, in miles.\r\n" );
document.write( "\r\n" );
document.write( "Then the rate by Austin   was    miles per hour,\r\n" );
document.write( "\r\n" );
document.write( "     the rate by Snelling was    miles per hours.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We are given that Austin traveled 1 mph faster than Snelling,\r\n" );
document.write( "so we can write this equation\r\n" );
document.write( "\r\n" );
document.write( "     -  = 1  mph.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "At this point, the setup is complete.\r\n" );
document.write( "To solve this equation, multiply both sides by 4*5 = 20, which is the common denominator.\r\n" );
document.write( "\r\n" );
document.write( "You will get then\r\n" );
document.write( "\r\n" );
document.write( "    5d - 4d = 20,\r\n" );
document.write( "\r\n" );
document.write( "       d    = 20.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, one way distance is 20 miles.    ANSWER\r\n" );
