ellie can edit an average of 160 pages of text in an 8 hour work day. what is her unit rate for the number of pages edited per hour?
\\(\frac{160\text{ pages}}{1\text{ hour}}\\)
\\(\frac{20\text{ pages}}{1\text{ hour}}\\)
\\(\frac{20\text{ pages}}{8\text{ hours}}\\)
\\(\frac{8\text{ pages}}{1\text{ hour}}\\)

Explanation:

Step1: Recall unit rate formula

Unit rate is total quantity divided by total time. So, pages per hour = total pages / total hours.

Step2: Substitute values

Total pages = 160, total hours = 8. So, \( \frac{160}{8} = 20 \).

Step3: Form unit rate

The unit rate is \( \frac{20 \text{ pages}}{1 \text{ hour}} \).

Answer:

B. \( \frac{20 \text{ pages}}{1 \text{ hour}} \)
