During one year, people in the U.S. older than 18 years old watched a total of 342 billion hours of television. The population of the U.S. older than 18 years old was about 209 million people.
On average, how many hours of television did each person older than 18 years old watch that year? Round to the nearest hour.
On average, how many hours per week did each person older than 18 years old watch that year? Round to the nearest hour.
342 billion / 209 million = 1,636.36364 = 1,636 hours per year
1,636 / 52 = ______ hours per week
31.4615385
To find the average number of hours of television watched per person, divide the total number of hours watched by the number of people.
342 billion hours / 209 million people = 1,637 hours per person.
To find the average number of hours watched per week, divide the average number of hours watched per person by the number of weeks in a year (52).
1,637 hours / 52 = 31.5 hours per week.
Rounding to the nearest hour, each person older than 18 years old watched approximately:
- 1,637 hours of television per year
- 32 hours of television per week.
To find the average number of hours of television watched per person older than 18 in the U.S. during the year, you need to divide the total number of hours of television watched (342 billion) by the population of people older than 18 (209 million).
Step 1: Convert the total number of hours of television watched to hours
342 billion hours = 342,000,000,000 hours
Step 2: Divide the total number of hours of television watched by the population of people older than 18
342,000,000,000 hours ÷ 209,000,000 people = 1,638.28 hours
So, on average, each person older than 18 in the U.S. watched approximately 1,638 hours of television in that year.
To find the average number of hours per week, you need to divide the average number of hours per year by the number of weeks in a year.
Step 1: Find the number of weeks in a year
There are approximately 52 weeks in a year.
Step 2: Divide the average number of hours (1,638) by the number of weeks (52)
1,638 hours ÷ 52 weeks ≈ 31.5 hours
So, on average, each person older than 18 in the U.S. watched approximately 31.5 hours of television per week.
