Explanation:
To find the speed of the pursuit ship relative to the cruiser you use the following relativistic equation:

u': relative speed
u: speed of the pursuit ship = 0.8c
v: speed of the cruiser = 0.6c
c: speed of light
You replace the values of the parameters to obtain u':

Hence, the relative speed is 0.384c
