A leap second is an extra second that is added now and then to a day, to adjust for changes in the Earth's rotation. The second was originally defined as 1/86400 of a day, but according to the modern definition, the second has a fixed duration, independent of the Earth's rotation.

How many seconds are there in eleven years?

You will have to figure out how many leap years. In this answer, I figured it based on if the leap year was on the 1st year. Then you would have one in your 1st, 5th and 9th year. Also figured that a year is 365 days and a leap year is 366 days. There are 31,536,000 sec in a year and 31, 622,400 sec in a leap year. 365dys x 24 hrs = 8760hrs a year 366dys x 24 hrs = 8784 hrs a leap yr 8760hrs x 60min=525,600min/yr 8,784hrs x 60min=527,040min/lp yr 525,600mins x 60sec=31,536,000sec/yr 527,040min x 60sec=31,622,400 sec/lpyr 31,536,000 x 8 regular years =252,288,000secs in 8 regular years 31,622,400 x 3 leap years = 94,867,200sec in 3 leap year 252,288,000sec +94,867,200sec = 347155200 347,155,200secs in 11 years if there are 3 leap years
