The designed speed for a project considered is a minimum value which means the highway design elements will meet or exceed the standards for the design speed. The maximum safe speed under normal condition is significantly greater than design speed
Recession velocity of a galaxy is related to the distance at which the galaxy is located. This relationship is given by the hubble constant, as follows:
Hubble constant is aproximate and 1 megaparsec (Mpc) is 3.26*10^6 light years. Rewriting for D:
