Because Earth's rotation is gradually slowing, the length of each day increases: The day at the end of 1.0 century is 1.0 ms longer than the day at the start of the century. In 61 centuries, what is the total of the daily increases in time (that is, the sum of the gain on the first day, the gain on the second day, etc.)?
The Attempt at a Solution
i'm honestly stuck, i'm not sure how to approach this problem, i converted the 61 centuries and added 61 ms to it because the time increases every 100 years by 1.0 ms.
thank you to all that help
