Final answer:
Using the concept of ratio and proportion, we find that it will take Susan 420 minutes to read 210 pages of the novel, based on her reading speed of 1 page every 2 minutes.
Explanation:
This problem involves a concept in Mathematics known as ratio and proportion. We are given that Susan can read 40 pages in 80 minutes, which simplifies to a ratio of 1 page per 2 minutes. Now, we want to find out how long it will take her to read 210 pages. Set up a proportion:
40 pages / 80 minutes = 210 pages / x minutes.
To solve this mathematically, cross-multiply and divide:
40 * x = 210 * 80;
x = (210 * 80) / 40;
x = 420 minutes.
Therefore, it will take Susan 420 minutes to read 210 pages of the novel at the same reading speed.
