Answer:
a) It will take andy 5/3 minutes ( 1 minute 40 seconds) to read 1 page
b) It will take andy 100 minutes to finish the book.
Step-by-step explanation:
Given;
a) It takes Andy 10 minutes to read 6 pages of his book
His rate is;
r = 10 minutes per 6 pages
r = 10/6 min/page
r = 5/3 minutes per page = 1 minute 40 seconds per page
It will take andy 5/3 minutes ( 1 minute 40 seconds) to read 1 page
b) To find the book;
He has already read 150 pages in his book that is
210 pages long.
Number of pages left = 210 - 150 = 60 pages
Time taken to read 60 pages t = 60 pages × 5/3 minutes per page.
t = 60 × 5/3 = 100 minutes
It will take andy 100 minutes to finish the book.
