Zack reads 180 pages of his summer reading book in 4 hours. How many pages will he finish in 5 hours

225 pages

Step-by-step explanation:

This is solved by first figuring out the rate of how many pages per hour is he reading. This can be found by dividing the pages read by the amount of hours to get 180 pages/4 hours= 45 pages per hour. Then to find out how many in 5 hours, you multiply 5 hours by 45 pages per hour. The hour unit cancels out and you are left with 225 pages. That is the answer.
