11400 years

 

[Ram97]

11400 years

I got 4 years. I just divided the given values

Pretty sure two half-lives thin
You had to divide them the opposite way.
You get 1/4 that way which is (1/2)^2
So 2 half lives.

Half life was 5700.
5700 x 2 = 11400

In varient 1. In the first part of question about Power I made a mistake. I multiplied by 60 instead of dividing but my working and formula were correct and in the second part of the question, my formula and working were correct but I used a wrong answer from the first part :/ So will they use error carried forward so I will get maximum mark in the second part? or they will just give me zero?

I was doing that way then I realised that age can't be so small so I divided it the other way around. Would I get any mark??

opinion is what can be denied. (e.g. maths is best subject)
fact is what can never be denied in any situation. (rose is red)
