Problem Analysis

To solve this problem, we need to calculate the number of days it will take for the girl to read the entire book. We are given that the book has 118 pages, and the girl initially reads 16 pages per day for 4 days, and then reads 18 pages per day. We need to find the total number of days it will take for her to read the entire book.

Solution

Let's break down the problem step by step:

1. Calculate the number of pages the girl reads in the first 4 days: 4 days * 16 pages/day = 64 pages. 2. Calculate the number of pages remaining in the book after the first 4 days: 118 pages - 64 pages = 54 pages. 3. Calculate the number of days it will take for the girl to read the remaining pages: 54 pages / 18 pages/day = 3 days.

Therefore, it will take the girl a total of 4 days (initial 4 days + 3 days) to read the entire book.

Answer

The girl will read the entire book in 4 days.
