Final answer:
To find the number of seconds in a leap year and a half, calculate the total seconds for 366 days and 182.5 days and sum them. The total is 47,390,400 seconds with a leap year, and 47,304,000 seconds without considering a leap year.
Step-by-step explanation:
To calculate how many seconds there are in a leap year and a half, you first need to know the number of seconds in a day, which is 1 day × 24 hr/day × 60 min/hr × 60 s/min = 86,400 s/day. A leap year has 366 days, so you multiply the number of seconds in a day by 366 to find the total seconds in a leap year. To calculate a year and a half, including one leap year, you would do the following:
- Leap year: 366 days × 86,400 s/day = 31,622,400 seconds
- Half of a regular year (182.5 days): 182.5 days × 86,400 s/day = 15,768,000 seconds
Add them together: 31,622,400 seconds + 15,768,000 seconds = 47,390,400 seconds in a leap year and a half. Without considering a leap year (or a regular year of 365 days), the calculation for a year and a half would be slightly different:
- 1 year: 365 days × 86,400 s/day = 31,536,000 seconds
- Half year: 182.5 days × 86,400 s/day = 15,768,000 seconds
Add them together: 31,536,000 seconds + 15,768,000 seconds = 47,304,000 seconds in a regular year and a half.
