Answer/Step-by-step explanation:
Exercise 5:
a. 180 pages was read in 5 days
Unit rate = pages per day = 180 pages ÷ 5 = 36 pages per day.
b. Number of pages of the book = 765 pages
Unit rate = 36 pages per day
Number of days to read the book = 765/36 = 21.25
It will take Kirk about 22 days to finish reading the book.
