Final answer:
It will take approximately 37.5 minutes to type 3 pages at a typing speed of 40 words per minute.
Step-by-step explanation:
To find the time it will take to type 3 pages, we need to determine how long it takes to type one page and then multiply it by 3. With a typing speed of 40 words per minute, we can calculate the time it takes to type one page as follows:
Number of words per page ÷ Typing speed = Time per page
500 words ÷ 40 words per minute = 12.5 minutes per page
Now, to find the time to type 3 pages, we multiply the time per page by 3:
12.5 minutes per page × 3 pages = 37.5 minutes
Therefore, it will take approximately 37.5 minutes to type 3 pages at a typing speed of 40 words per minute.
