Step 1. Since Emeline can type at a constant rate of 1/4 pages per minute, she will write 1 page in
[tex]\frac{1}{4}\text{pages in 1minute }\longrightarrow\frac{1}{4}\cdot4=1page\text{ in }1\cdot4=4\text{ minutes}[/tex]She writes 1 page in 4 minutes.
Step 2. Now that we know how much it takes Emeline to write one page, we multiply that by the number of pages that she has to write for the article:
[tex]4\text{ minutes }\cdot7=28\text{ minutes}[/tex]It will take her 28 minutes.
Answer: 28 minutes
