Final answer:
Krista will take approximately 8.06 minutes to type her 4-page essay at a rate of 62 words per minute. Technology like personal computers greatly enhances productivity over manual typing.
Step-by-step explanation:
Krista can type 62 words per minute and has a 4-page essay with each page containing 125 words to type. To calculate how long it will take her to type the essay, we first determine the total number of words in the essay by multiplying the number of pages by the number of words per page.
- 4 pages × 125 words/page = 500 words total
Next, we divide the total number of words by the number of words Krista can type per minute.
- 500 words ÷ 62 words/minute ≈ 8.06 minutes
So, it will take Krista approximately 8.06 minutes to type the entire essay. It is clear that modern technology, such as a personal computer and word processing software, increases productivity significantly compared to manual methods.
