The book contains over 66 chapters.
She reads at an average rate of 3 words per second.
There is an average of 20 words per sentence and an average of 6 sentences per paragraph.
The average amount of paragraphs in a chapter is 12.
About every 25 minutes Dove gets distracted and each distraction lasts about 2 minutes.
If Dove starts reading the book at 9:30am, what chapter will she be on at 11:45am?
:
Find how many words in a chapter
20 * 6 * 12 = 1440 words
;
Find how many words he reads in 25 minutes
3 * 60 * 25 = 4500 words in 25 minutes, however, for 2 min he does not read
4500 words in 27 min so that is
4500%2F27 = 167 words per min average
:
Find how many minutes from 9:30 to 11:45: 120 + 15 = 135 minutes
Find how many chapters read in this time
%28135%2A167%29%2F1440 ~ 16 chapters by 11:45
I should say he will be on Chapter 15 at 11:45
