Answer 3

Problem Analysis

The problem states that a student read 90 pages of a book in 3 days. We need to determine how many pages the student will read in 6 days, assuming that I read the same number of pages per day.

Solution 1: Proportional Method

To solve this problem, we can use a proportional method. Since the student read 90 pages in 3 days, we can set up a proportion to find the number of pages read in 6 days:

Pages read in 3 days / 3 = Pages read in 6 days / 6

We can solve this proportion by cross-multiplying and then dividing:

Pages read in 6 days = (Pages read in 3 days / 3) * 6

Let's calculate the result using this method.

Solution 2: Doubling Method

Another way to solve this problem is by using a doubling method. Since the student read 90 pages in 3 days, we can double the number of pages read each day to find the number of pages read in 6 days.

Let's calculate the result using this method as well.

Calculation

Solution 1: Proportional Method Pages read in 6 days = (90 / 3) * 6 = 180 pages

Solution 2: Doubling Method Day 1: 90 pages Day 2: 90 * 2 = 180 pages Day 3: 180 * 2 = 360 pages Day 4: 360 * 2 = 720 pages Day 5: 720 * 2 = 1440 pages Day 6: 1440 * 2 = 2880 pages

Therefore, the student will read 180 pages in 6 days using the proportional method and 2880 pages using the doubling method.
