Karen read 20 pages of her book in a half hour if she reads for 3 hours at that same rate about how many pages of her book can she read
If Karen read 20 pages in half an hour, she read at a rate of 20 pages / 0.5 hours = 40 pages per hour.
Therefore, if she reads for 3 hours, she can read 40 pages/hour * 3 hours = 120 pages of her book.
To find out how many pages Karen can read in three hours, we need to determine her reading rate per hour and then multiply that rate by three.
Given that Karen read 20 pages in a half hour, we can calculate her reading rate per hour as follows:
20 pages / 0.5 hours = 40 pages per hour
Now, we can calculate how many pages Karen can read in three hours:
40 pages per hour * 3 hours = 120 pages
Therefore, Karen can read approximately 120 pages of her book in three hours.
20/0.5 = x/3
Cross multiply and solve for x.
