Let be a Banach space and let denote the space of Orlicz -valued integrable functions on the unit interval equipped with the Luxemburg norm. In this paper, we present a distance formula dist, where is a closed subspace of , and . Moreover, some related results concerning best simultaneous approximation in are presented.
