Final answer:
To calculate the extrapolated exercise time over a month and a year, multiply the weekly exercise duration by the average weeks in a month and then by the total months in a year, resulting in 645 minutes/month and 7740 minutes/year respectively.
Step-by-step explanation:
The question involves calculating the extrapolation of exercise duration over different periods of time, such as a month and a year, based on a weekly exercise routine. First, let's calculate the exercise time for a month. The recommendation is 30 minutes of walking per day, 5 days a week.
- Calculate weekly exercise: 30 minutes/day × 5 days/week = 150 minutes/week.
- Calculate monthly exercise (average 4.3 weeks per month): 150 minutes/week × 4.3 weeks/month = 645 minutes/month.
Next, we calculate the exercise time for a year:
- Calculate annual exercise: 645 minutes/month × 12 months/year = 7740 minutes/year.
