It took lisa 2 hours to read the first 100 pages of a book. then she read the last 44 pages in 1 hour. how many pages did she read per minute for the whole book? answer a. 0.75
b. 0.8
c. 1.2
d. 1.25

There are 60 minutes in an hour and altogether it took her 3 hours yo read the book. This is the same as 180 minutes.
So you have to divide the number of pages by the time it took for her to read them:
144 ÷ 180 = 0.8
The answer is B. 0.8
Hope this helped :)
