Consider a noisy station that detects transmissions and disrupts them by beginning a competing transmission as soon as it hears the beginning of the transmitted frame, thereby causing a collision. Assume the detector machine, which is on this Ethernet with bandwidth 10 Mbps, detects collision during the transmission of its 12^th bit on the wire (including any preamble). If the speed of the signal in the wire is 2*10^8 m/s, then the distance( in meters ) of the noisy station from the detector machine is
