Two identical spaceship A and B, each 200m long in its rest frame, pass one another travelling in opposite directions. According to a passenger in spaceship B, the relative velocity of the two ships is 0.58c. What is the length of each spaceship in a reference frame in which both are of equal length?

2. Relevant equations

I'm kinda new to the interface, can't seem to type out the formulas but i used:

Lorentz Factor = 1 / *square root* [1 - beta^{2}]

3. The attempt at a solution

I found the length of space ship A in view of the passenger in B, which is 163m.

That would, by right be the length of B in view of A, right? What perplexes me the most is the las part of the question; Length of each spaceship in a reference frame in which both are of equal length. Would that be the frame of Earth?

Please advise =S
