Question

Approximately how many seconds are there in a century (to two sig figs)?

Answer 1

There are approximately 3.2 x 10^7 seconds in a century.

Step-by-step explanation:

To calculate the number of seconds in a century, we need to multiply the number of seconds in a minute, minutes in an hour, hours in a day, and days in a year. First, we have 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. Then, we need to consider leap years, which occur every 4 years. In a year, we have 365 days, so in a century, we have 100 years. Therefore, the calculation is: 60 seconds/minute * 60 minutes/hour * 24 hours/day * 365 days/year * 100 years = 31,536,000 seconds in a century. Rounded to two significant figures, the answer is approximately 3.2 x 10^7 seconds.
