# GSM8K Problem 8

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?

Reason step by step, then give ONLY the final answer on the last line as \boxed{ANSWER}.

Let's break down the problem step by step:

1. Carla can download 2 GB/minute.
2. The total size of the file is 200 GB.
3. 40% of the way through the download means Carla has downloaded 0.4 * 200 GB = 80 GB before the restart.
4. The restart takes 20 minutes.
5. After the restart, Carla has to download the entire file again, which is 200 GB.
6. To download 80 GB at a rate of 2 GB/minute, it would take 80 GB / 2 GB/minute = 40 minutes.
7. Adding the 20 minutes for the restart, the total time to download the file is 40 minutes + 20 minutes = 60 minutes.

So, it takes Carla 60 minutes to download the file.

\boxed{60}
