conversations.value: She spends this long researching and editing her essay 45 min + 75 min = 120 min.
  Converting the minutes to hours for researching and editing is 120 / 60 = 2 hours.
  She spends this long writing the essay 6 x 30 min = 180 min.
  Converting the minutes to hours for writing the essay is 180 / 60 = 3 hours.
  The total hours Rachel spends completing the essay is 2 + 3 = 5 hours.
