Jane gets in her spaceship on her twenty-fifth birthday and flies to the star Vega at a constant velocity v. She is just turning age 31 when she reaches the Vega system.
What is the speed of her ship, as a fraction of the speed of light c?
The Attempt at a Solution
I have attempted this 7 times. I have 3 chances left. I found out that the distance to Vega to be 25.3 Light years and i converted that to meters and then i converted 6 years to seconds and I still could not get the right answer. I have to express the answer as a fraction of the speed of light, but i continue to get a value that is 4x the speed of light. Any ideas?
Thanks in advance
