]we will be solving problems in Real Life by using the methods learned in week 4 for solving systems of equations.  Most everyone has a fear of word problems because you haven’t had much experience in solving them.  If you just take them one step at a time, you will find them manageable and build your confidence in your ability to successfully tackle any word problem you meet.

Here is an example to get us started.  I am working out the entire problem for you, but in your initial post you only need to set up the situation and leave solving the problem to a classmate (see prompt given above).

APPLICATION PROBLEM:       DISTANCE = RATE X TIME A boat’s crew rowed 12 miles downstream, with the current, in 1.5 hours.  The return trip, against the current, covered the same distance but took 4 hours.  Find the crews rowing rate in still water and the rate of the current.

The relationship we need to use is Distance = Rate x Time.  We will have two equations: one for the trip downstream and one for the trip upstream.  We have two variables: crews rowing rate in still water and rate of the current.

Let w = crews rowing rate in still water

Let c = rate of the current

Downstream: Distance = Rate x Time    Rate will be w+c (rate in still water + current)

(1)                     12     = (w+c) 1.5 = 1.5w+1.5c

Upstream: Distance = Rate x Time    Rate will be w-c (rate in still water – current)

(2)                    12      = (w-c) 4 = 4w-4c

One approach is to simplify the equations before solving the system.

(1)     12=1.5w+1.5c divide both sides by 1.5

8 = w + c

(2)     12 = 4w=4c   divide both sides by 4

3 = w – c

Use Elimination on the two equations           8 = w+c
3 = w-c      After adding the two equations we have          11 = 2w     divide by 2

w = 11/2 = 5.5 Use this value to solve for c.

w+c = 8

5.5+c = 8

c = 8 – 5.5

c=2.5

Therefore, the rate of the current is 2.5 and the rate of the crew rowing in still water is 5.5. I can’t wait to see your posts.  You may use a scholarly resource, just remember to cite it.

• ### Is there a possibility of plagiarism in my completed order?

We complete each paper from scratch, and in order to make you feel safe regarding its authenticity, we check our content for plagiarism before its delivery. To do that, we use our in-house software, which can find not only copy-pasted fragments, but even paraphrased pieces of text. Unlike popular plagiarism-detection systems, which are used by most universities (e.g. Turnitin.com), we do not report to any public databases—therefore, such checking is safe.

We provide a plagiarism-free guarantee that ensures your paper is always checked for its uniqueness. Please note that it is possible for a writing company to guarantee an absence of plagiarism against open Internet sources and a number of certain databases, but there is no technology (except for turnitin.com itself) that could guarantee no plagiarism against all sources that are indexed by turnitin. If you want to be 100% sure of your paper’s originality, we suggest you check it using the WriteCheck service from turnitin.com and send us the report.

• ### I received some comments from my teacher. Can you help me with them?

Yes. You can have a free revision during 7 days after you’ve approved the paper. To apply for a free revision, please press the revision request button on your personal order page. You can also apply for another writer to make a revision of your paper, but in such a case, we can ask you for an additional 12 hours, as we might need some time to find another writer to work on your order.

After the 7-day period, free revisions become unavailable, and we will be able to propose only the paid option of a minor or major revision of your paper. These options are mentioned on your personal order page.
