Did the question specify which 100 years?

There were 25 leap years in the last 100 years, but the year 1900 wasn't a leap year.

Every year ending in 00 is not a leap year.

The year 2000 was a leap year, but the year 2100 will not be a leap year.

The years 1600, 2000 and 2400 are leap years,
while 1700, 1800, 1900, 2100, 2200 and 2300 are common years.
By this rule, the average number of days per year is
365 + ​1⁄4 − ​1⁄100 + ​1⁄400 = 365.2425.

As 00 to 100 inclusive would be 101 years, which isn't a century, I think it would help if you gave the exact wording of the problem.

None of the years from 1AD to 100AD were leap years. We weren't even on the current calendar then (at least for most of the century) and leap years weren't introduced until the 16th(?) century (again guesswork, but the calendar wouldn't have got 11 days out with them).

"The lighter the faster", how much weight does Mamma Earth
need to lose in order to achieve the exact speed that'll result
in a perfect 360-day return trip? Imagine: 12 30-day months!
