Answer:
The day would be 3.125 seconds longer in 25 centuries.
Step-by-step explanation:
Let's break it down.
Each year, 1250 microseconds are added to the planet's day.
We need to find how long a day would be in 25 centuries.
A century is 100 years.
A second is 1,000,000 microseconds.
[tex]100*25=2500\\\\2500*1250=3125000\\\\\frac{3125000}{1000000}=\frac{3125}{1000}=\frac{3.125}{1}=3.125[/tex]
The day would be 3.125 seconds longer in 25 centuries.
