Hi,

Age of Earth is equal to

  1. A solar day
  2. A lunar day
  3. An astronomical day
  4. None of these

Which is the correct one and how?

Do you have any idea how old the Earth is?
 
According to my book:

1.4 x 107 s
 
and do you have any idea how long each of those other things is?
 
It's approximate value. nope, I don't have any idea about this.

That's why I asked it here !
 
perhaps you would find it informative to look them up.

The age of the Earth is on the order of 4.5✕109 years .
