Personal Comment: I have not found an answer to this, but I am happy with the suggestions I got.

The 2 hour Enigma

Story:
Suppose that you were in a very powerful rocketship. Say that you accelerated away from the Earth so that the first billion miles took you an hour of time, the second billion miles took you a half hour of your time, the third billion miles took you a quarter hour, and so on. In general, it would take you 1/2n hours to cover the n+1st billion miles.

Enigma: Where will you be after two hours?


Solution:I recieved several answers on this question. The lowest was 6 miles(I think they meant 6 billion)... And the highest was infinite miles. This problem represents an infinite geometric series which you actually can't reach the 2 but time moves at a constant speed... Doesn't it? Einstein suggested that time for the travelers would slow down as they approaced infinity so that they could not reach it. Any comments on this matter are welcome.
