Velocity required to reach star in 10 onboard years

[alanthreonus]

Homework Statement

You wish to travel to the Pleiades (at a distance of 130 pc) in 10 years, according to the clock
that you carry. How fast do you have to travel to accomplish this (express the velocity as a
fraction of speed of light, v/c)?

Homework Equations

<br /> \Delta T = \gamma \Delta T_0<br />

The Attempt at a Solution

I've been stuck on this for hours, and I really don't know how I'm supposed to set this up. If someone could just help me set it up, I can do all the calculations myself.

d=vt. You know t=10 years. d can be found via the length contraction formula: to an onboard observer, the distance to the Pleiades seems contracted by a factor of gamma.
