Saitama (1 punch man) Can run faster the speed of light

Saitama jumped at a insane speed from the moon to the earth and it took him 1.5 seconds to reach the earth. The distance between the moon and the earth is 384,400 km concluding that saitamas speed was 256,266 km/s the speed of light is 299,792 km/s. so the since saitama was not at full speed/power it can be concluded that saitama can go beyond the speed of light.

Saitama's Power

Saitama has not shown his full power yet, however over 12 episodes we have seen him smash a giant meteors easily that threatened a whole city (city z) he also defeated lord boros and survived a punch to the moon without a single scratch concluding that he could probably 1 punch the earth.
