Question

3. The students in Ms. Hill's class are reading a 325-page book. There are about90,000 words in the book. Ms. Hill said the students should try for a reading rateof 200 words per minute for greatest comprehension. Molly rread 65 pages of thebook in 80 minutes. What is Molly's reading rate in words per minute? *

Answer 1

ANSWER

225 words per minute.

EXPLANATION

Assuming that every page of the book has the same number of words, then each page has:

$\frac{90,000\text{ words}}{325\text{ pages}}=\frac{3600}{13}$

3600/13 words.

If Molly read 65 pages:

$\frac{3600}{13}\times65=18,000$

then she read 18,000 words. All this in 80 minutes. So her reading rate is:

$\frac{18,000\text{ words}}{80\text{ min}}=225\frac{words}{\min }$

Molly's reading rate is 225 words per minute
