conversations.value: Find the answer to this math problem: Minnie is making a playlist of songs for a party she will be throwing. She wants the playlist to be an hour long. She has added 16 three-minute songs to the playlist. How many four-minute songs does she have to add to make sure the playlist is an hour long?
conversations.from: assistant
conversations.value: An hour is equal to 60 minutes.
  Minnie has 16 * 3 = 48 minutes of songs already on the playlist.
  She has to fill 60 - 48 = 12 more minutes.
  Thus, she needs to add 12 / 4 = 3 four-minute songs.
