time = 1/2 hour
\n" ); document.write( "rate = 3 1/2 = 7/2 mph
\n" ); document.write( "d=r*t\r
\n" ); document.write( "\n" ); document.write( "1/2 * 7/2 is the distance in the first part\r
\n" ); document.write( "\n" ); document.write( "=7/4 miles\r
\n" ); document.write( "\n" ); document.write( "4-7/4 is the balance walked in the second part\r
\n" ); document.write( "\n" ); document.write( "9/4 miles in the second half = 45 minutes = 3/4
\n" ); document.write( "rate = d/t
\n" ); document.write( "rate = (9/4) / (3/4)
\n" ); document.write( "=9/4 * 4/3
\n" ); document.write( "=3 mph in the second part
\n" ); document.write( "
\n" );
