It takes Ty 4 hours 30 minutes to read his favorite book, reading at a constant rate of 100 pages every 50 minutes. How many pages are in Ty's favorite book?

540 pages

Step-by-step explanation:

100 pages = 50 mins

??? pages = 270 mins (converted 4hrs 30 mins to minutes)

Now you could cross multiply to find what the number of pages are:

100 pages x 270  mins = 50 mins x ??? pages

27000 = 50 mins x ??? pages

27000/50 = ??? pages

540 = ??? pages

So there are 540 pages in his favourite book.

To find the perimeter you have to add all sides.

36 + 36 + 36 + 36 = 144

The perimeter of the square is C. 144 inches

Hope this helps. :)
