While a CD player is reading the outer edge of an audio CD the disc spins at approximately 3.33 revolutions per second. The radius of a CD is 0.06 meters and the data transfer rate is 1.2 million bits per second (a bit is the smallest piece of information one can have - it is either a one or a zero). How many bits are stored per meter on the outer rim of a CD to the nearest thousand?
