It indicates that the fish had ancestors that did have eyes that were used to see, and then, because of natural selection and evolution, the fish evolved to not need eyesight, thus being blind, but, did not evolve so that there were no eye sockets etc.

9. You find a rock 7,500 km away from the nearest seafloor spreading center. The plate is spreading at 5 cm/year, how old is the
Anna [14]
The answer is 150,000,000 years (150 million years)

Let's first convert 7,500 km to cm:
1 km = 100,000 cm
7,500 km = 7,500 · 1 km = 7,500 · 100,000 cm = 750,000,000 cm

Now, it is known that the plate is spreading at 5 cm per 1 year. Make a proportion:
5 cm : 1 year = 750,000,000 cm : x
x = 750,000,000 cm · 1 year ÷ 5 cm = 150,000,000 years
