conversations.value: Find the answer to the math problem: Rachel is an artist. She posts a speed painting video each week on her Instagram account to promote her work. To save time, she paints and records 4 videos at a time. It takes her about 1 hour to set up her painting supplies and her camera. Then she records herself painting for 1 hour per painting. She takes another 1 hour to clean up. Each video takes 1.5 hours to edit and post. How long does it take Rachel to produce a speed painting video?
conversations.from: assistant
conversations.value: Rachel spends 1 + 1 = 2 hours setting up and cleaning up.
  She paints for 1 hour x 4 paintings = 4 hours.
  Then she edits 1.5 hours x 4 videos = 6 hours.
  She spends 2 + 4 + 6 = 12 hours to make 4 videos.
  So Rachel spends 12 / 4 = 3 hours on each video.
