How long will it take her to reach the bottom of the hill, assuming she starts from rest and accelerates uniformly, if the elevation change is 340 m?

What does it mean "the elevation change is 340 m" ?

My answer was 12.43 s
Is it right? If not how do I do it?

The most ignorant thing and dangerous thing in the world is to have an opinion without knowing the facts - so please note:

1.Why can’t we do it now? – quite simply, there is no Saturn V rocket and there is no lunar lander (LEM). It needed the phenomenal power of this giant 360 foot rocket to get a manned probe beyond Earth’s orbit, and it needed the ultra-lightweight but immensely high-tech LEM to land on the moon. Both machines were multi-billion dollar developments. Both are no more.
2.What happened to the Apollo? – read the history. Americans were wholly caught up in the Vietnam war, with massive and violent demonstrations going on. People saw the space program as a huge waste of money when there were so many social and international problems to attend to.
3.Apollos 18-20 were cancelled because of lack of taxpayer interest. There were plans to take along a small “flyer”, so astronauts could get around quicker.

All living organisms have a basic instinct for survival. This is either by deriving nutrition that can be turned into energy or by reproduction. This is done by instinct. But instinct is inherited knowledge or at least that is what I have been taught.

My question to evolutionists is how did the first living organism gain this instinctive knowledge? How did it “know” to divide for its survival?
