conversations.value: Explain how to solve this math problem: Three train stations are 2 hours apart from one another. Kira travels from the first station to the third, taking a 30 minutes break at the second station. What's the total time, in minutes, that Kira takes to travel between the first and third station?
conversations.from: assistant
conversations.value: Travel between the three stations takes 2+2 = 4 hours
  The total time for the journey is 4*60 = 240 minutes.
  If Kira takes a 30-minute break, her journey takes 240+30 = 270 minutes
