\n" ); document.write( "On that day, she spent twice as much time attending meetings as making telephone calls and spent 0.5 hr. longer writing e-mails and making telephone calls.
\n" ); document.write( "-------------
\n" ); document.write( "Let telephone call time be \"x\" hr.
\n" ); document.write( "Meeting time was \"2x\" hr.
\n" ); document.write( "Email time was 0.5 hrs.
\n" ); document.write( "----------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "x + 2x + 0.5 = 7.5 hr
\n" ); document.write( "3x = 7
\n" ); document.write( "x = 7/3 hr = 140 minutes (time for telephone calls)
\n" ); document.write( "2x = 14/3 hr = 280 minutes (meeting time)
