Heart rate = 0.6(220-a)
\n" ); document.write( "where a represents the age of the person in years.
\n" ); document.write( "Determine the optimum heart rate for a 35-year-old runner.
\n" ); document.write( "----------------------------
\n" ); document.write( "H(35) = 0.6(220-35)
\n" ); document.write( "= 0.6(185)
\n" ); document.write( "= 111 beats per minute
\n" ); document.write( "==============================
