You are in a spacecraft that is traveling at 0.9c (according to the passenger), and you want to get to a planet that is 11 light years away. How long will it take to get to the planet ?

This may seem like a simple problem but it's been bugging me. I answered this question by using the simple time = distance / speed since the person is in the same frame of reference as the space craft, is this correct?
