Arithmetic Reasoning
As an ASVAB tutor, I focus very heavily on the review of Arithmetic Reasoning.
One of the 15 subtopics I focus on is distance and rate.
Yesterday I presented a question on rate.
If a copy machine can copy 15 pages in a minute, how many pages can it copy in 3 ½ hours.
- 5 pages
- 900 pages
- 2700 pages
- 3150 pages
To solve this problem, first change 3 ½ hours into minutes. There are 60 minutes in an hour, so there are 180 minutes in 3 hours. There are 30 minutes in a half hour.
The total amount of minutes in 3 ½ hours is 180 + 30 = 210 minutes.
If the copy machine copies 15 pages in a minute for 210 minutes, multiply 210 by 15 to figure out the total number of copies.
210 x 15 = 3150.
The correct answer is 3150 pages.
Did you know how to answer this problem?
