conversations.value: Carla is downloading a 200 GB file. Normally she can download 2 GB/minute, but 40% of the way through the download, Windows forces a restart to install updates, which takes 20 minutes. Then Carla has to restart the download from the beginning. How load does it take to download the file?

conversations.value: First find how many gigabytes are in 40% of the file: 200 GB * 40% = 80 GB
  Then divide that number by the download rate to find the time until Windows restarts: 80 GB / 2 GB/minute = 40 minutes
  Then find the time to download the whole file after the restart: 200 GB / 2 GB/minute = 100 minutes
  Then add the time to download 40% of the file, to download the whole file, and to wait for Windows to update: 40 minutes + 100 minutes + 20 minutes = 160 minutes
