Question

Can a parent ever be exactly twice as old as his or her child?

Answer 1

Yes, if someone were to have a kid at 18, and 18 years later, the parent is then 36, so therefore it is possible to have a parent that is twice as old as there kid.

Answer 2

Yes I do believe that it's true, because if some one has a child at the age of 20, and then when the child turns 20 years old, the parent will be 40 years old
