A useful and easy-to-remember approximate value for the number of seconds in a year is ? X 107. Determine the percent error in this approximate value. (There are 365.24 days in one year.)

Solution 15E Step 1: Number of hours in a day, 1 day = 24 hours We know that, 1 hour = 60 minute 1 minute = 60 seconds. So, total number of seconds in 1 hour = 60 × 60 seconds = 3600 seconds Total number of seconds in 1 day = 24 × 3600 seconds = 86400 seconds Total number of seconds in 1 year = 365.24 × 86400 seconds, T = 3.16 × 10 seconds 7
