Each station in IEEE 802.5 with one bit-delay is 46 meters apart from its neighbours stations. Token is of 3B and propogation speed is 2.3x108 m/sec. To avoid overlapping in the 4Mbps token ring the monitor must insert 15 bits of artificial delay into the ring. How many stations are there in the ring ?
a) 9 c) 11
