Prompt
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?
Answer guidance
First find how many gigabytes are in 40% of the file: 200 GB * 40% = <<200*40*.01=80>>80 GB Then divide that number by the download rate to find the time until Windows restarts: 80 GB / 2 GB/minute = <<80/2=40>>40 minutes Then find the time to download the whole file after the restart: 200 GB / 2 GB/minute = <<200/2=100>>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 = <<40+100+20=160>>160 minutes #### 160
