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.
Kim is reading a book with 380 pages. She read 20 pages each day until she reached Part 2 of the book. Part 2 of the book is 160 pages long. She uses the equation 380−20𝑑=160
