Understanding Printing Times: A Case Study with Nina's Thesis

How long will it take Nina to print 2 copies of her 1400-page thesis on an inkjet printer that prints 4 pages per minute?

• A. 350 minutes
• B. 700 minutes
• C. 1400 minutes
• D. 2800 minutes

Answer: (B)

To determine the time it takes for Nina to print 2 copies of her 1400-page thesis, you first need to calculate the total number of pages she will print. Since she is printing 2 copies, you multiply the number of pages in one thesis by 2: 1400 pages × 2 copies = 2800 pages. Next, since the printer prints at a rate of 4 pages per minute, you can find the total time taken by dividing the total number of pages by the printing speed: 2800 pages ÷ 4 pages per minute = 700 minutes. This calculation demonstrates that Nina will need a total of 700 minutes to print both copies of her thesis, making it the correct answer. Understanding this process emphasizes the importance of breaking down the problem into manageable parts, which is crucial for successfully tackling similar questions in the future.

When tackling practical problems, understanding the math behind them can seem a little daunting—especially when it comes to real-life scenarios like printing a thesis. Picture this: Nina needs to print two copies of her 1400-page thesis on her trusty inkjet printer. Now, how long do you think it would take her? Spoiler alert, the answer is 700 minutes. Let’s break it down together, shall we?
