Answer:
Henry has read per minute 3 pages.
Step-by-step explanation:
Given:
Henry is an avid reader. He devours 90 pages in half-an-hour.
Now, to find pages Henry has read per minute.
Let the number of pages Henry has read per minute be [tex]x.[/tex]
Number of pages he devours in half-an-hour = 90 pages.
So, as half an hour is 30 minutes.
Thus, number of pages he devours in 30 minutes = 90 pages.
Now, to get the pages he has read per minute:
According to question:
[tex]30x=90[/tex]
Dividing both sides by 30 we get:
[tex]x=3.[/tex]
Therefore, Henry has read per minute 3 pages.
