Hey i dont know if you still need this, but in response to your second question you would have to use the lorenz transformations to get that answer in a reasonable fashion.

That problem with the bike actually comes from a scifi novel where c=60mi/h and it was interesting to see how things changed from his perspective as well as the fact that as he got going really fast it became immensly harder to increase his speed.

It's actually pretty simple to get the answer using the ordinary time dilation equation. However, I would argue very strongly that the correct answer to the question as stated is not 30 years, but it is $10\gamma = 16.7$ years.
