To solve this question, we need to first find out the total number of seconds in a month. We will assume a month to have 30 days for simplicity.
We know there are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day.
First, calculate the total number of seconds in an hour by multiplying the number of seconds in a minute by the number of minutes in an hour:
60 seconds/minute * 60 minutes/hour = 3600 seconds/hour
Next, calculate the total number of seconds in a day by multiplying the number of seconds in an hour by the number of hours in a day:
3600 seconds/hour * 24 hours/day = 86400 seconds/day
Then, calculate the total number of seconds in a month by multiplying the number of seconds in a day by the number of days in a month:
86400 seconds/day * 30 days/month = 2592000 seconds/month
So, there are 2,592,000 seconds in a 30-day month.
Given that one computer is purchased every two seconds, we would then divide the total number of seconds in a month by 2 to find out how many computers are purchased in a month:
2592000 seconds/month ÷ 2 = 1296000 computers/month
Therefore, it's estimated that 1,296,000 computers are purchased each month in North America.
