Final answer:
Nina will take 175 minutes to print 2 copies of her 1400-page thesis paper, given that her inkjet printer prints 4 pages/minute.
Step-by-step explanation:
To find out how long it will take Nina to print 2 copies of her 1400-page thesis paper on an inkjet printer that prints 4 pages/minute, we can use the formula:
Time (in minutes) = Total number of pages / (Printer speed in pages/minute x Number of copies)
Using the given values:
Time = 1400 / (4 x 2) = 1400 / 8 = 175 minutes.
So, it will take Nina 175 minutes to print 2 copies of her thesis paper.
