i looked on the top of my book and it says 75 years.
OK. Let's take 75 years.
Here's your original problem:
it is estimated that in an average lifetime a person watches about 105,000 hours of TV.
at this rate, about how many hours per day does a person watch TV?
75 * 365 * 24 = 657,000 hours
105,000 / 657,000 = 0.159 hours = about 10 minutes a day.
This doesn't seem right, does it?
Please check your figures again or ask your teacher to help you.
thank you anyways
It seems like you're indicating that you found a number, "75 years," on the top of a book. Without further context, it is difficult to determine the exact meaning of this number. However, I can provide some guidance on how to interpret it:
1. Book Title: Check if the number is mentioned as part of the book title. If it is, then it could be a significant date or a term related to the content of the book.
2. Book Edition: The number might indicate the edition of the book. Publishers often include the edition number on the cover or spine.
3. Copyright Notice: Look for a copyright notice on the book. This could indicate the year the book was originally published or the most recent edition.
4. Series or Volume: If the book is part of a series or part of a multi-volume set, the number could represent the position of the book within the series or set.
5. Pagination: Occasionally, books may have page numbers or headers that include a time reference. Check if the number corresponds to a specific page, chapter, or section that could provide more context.
If none of these suggestions help, provide more details about the book or the context of the number, and I'll be glad to assist you further.
