To find the number of days it took Kim to read Part 1 of the book, we can solve the equation 380 - 20d = 160.

Subtracting 160 from both sides of the equation, we get:

380 - 160 = 20d

220 = 20d

Dividing both sides of the equation by 20, we get:

d = 11

Therefore, it took Kim 11 days to read Part 1 of the book.
