60 mph EXAMPLE 3
It takes Andy 10 minutes to read 6 pages of his book. He has already read 150 pages in his book that is
210 pages long. Find how long it takes Andy to read 1 page and also find how long it will take him to
finish his book if he continues to read at the same speed.
by 6:

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.
