1. The problem statement, all variables and given/known data Suppose you decide to travel to a star 65 light-years away at a speed that tells you the distance is only 25 light-years. How many years would it take you to make the trip? 2. Relevant equations ∆t=∆t0/(√ (1−v2/c2 )) / ∆t0 = ∆t √(1−v2/c2) L=L0√ (1−v2/c2) 3. The attempt at a solution I've attempted to use the length contraction equation to find the velocity (v=c√(1-(25/65)^2) but when I plug that into the time dilation equation I don't get the correct answer. I get 25 when the answer should be 27. Where am I going wrong?
