const output = function(...data) {
  process.stdout.write(data.join(''));
};

const main = function(hour, minute) {
  hour = +hour;
  minute = (minute / 60) || 0;

  if (!hour) {
    throw new Error('No time was given.');
  }

  hours = hour + minute + 9.5;

  hour = hours >> 0;
  minute = hours * 60 % 60;

  if (hour < 10) {
    output(0);
  }

  output(hour, ' ');

  if (minute < 10) {
    output(0);
  }

  output(minute, '\n');
};

main.apply(undefined, process.argv.slice(2));
