Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Sarah is checking out books from the library to read on vacation. She can read 40 words per minute. The books she is checking out have 100 words per page and are 80 pages long. She will be reading for 20 hours. How many books should she check out?

### Response:
Each book has 8,000 words because 100 x 80 = <<100*80=8000>>8,000
She can finish each book in 200 minutes because 8,000 / 40 = <<8000/40=200>>200
She is traveling for 120 hours because 20 + 100 = <<20+100=120>>120
She needs to bring 6 books because 120 / 200 = <<120/200=0.6>>0.6
