conversations.value: Mark is baking bread. He has to let it rise for 120 minutes twice. He also needs to spend 10 minutes kneading it and 30 minutes baking it. How many minutes does it take Mark to finish making the bread?
conversations.from: assistant
conversations.value: First find the total rise time: 120 minutes * 2 = 240 minutes
  Then add the rise time to the baking and kneading time: 240 minutes + 10 minutes + 30 minutes = 280 minutes
