Question

Meg is printing a term paper for class at the rate shown in the table below. If the term paper is 60 pages long, how many total minutes will it take to print out? Assume that the printer prints the pages at a constant rate.

Answer 1

You may use the data from any one column of the table to calculate the approx. printing rate. Suppose we choose to use the data (4 minutes, 10 pages). Then the printing rate is 10/4 pages per minute, or (5/2) pages per minute, or 2.5 pages per minute.

How long would 60 pages take to print? We want to eliminate the unit "pages" in favor of "min." So, multiply "60 pages" by (2 min) / (5 pages). "pages" will cancel:

60 pages 2 min
------------- * -------------- = 24 minutes (answer)
1 5 pages

Answer 2

Pretty sure the answer is 24 because 60 pages divided by 15 pages (6 mins each) = 4

So, 4 times 6 (since we have to print 15pages 4 times) = 24minuets
