Answer:
The speed of Lilac is 0.422 times of the speed of light.
Explanation:
Given that,
Length of the spaceship Lilac at rest, 
When Lilac passes Earth, observers there measure its length to be 688 m, L = 688 m
We need to find the speed of light is Lilac moving with respect to Earth. The formula of length contraction is given by :
So, the speed of Lilac is 0.422 times of the speed of light.
