Question

There are 1,000,000 microseconds in a second. If the length of a day on a planet increases by 1,250 microseconds

Answer 1

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.

$100*25=2500\\\\2500*1250=3125000\\\\\frac{3125000}{1000000}=\frac{3125}{1000}=\frac{3.125}{1}=3.125$

The day would be 3.125 seconds longer in 25 centuries.
