Consider a network with 3 stations A, B and C connected through a HUB. Distance . between A and B is 1500 meters, between A and C 1200 meters and between B and C 700 meters. The channel rate is 100 Mbps. The speed of propagation of the communication medium is 2x105 km / s. For simplicity, let's consider that the HUB does not introduce delay in the signal propagation. I If A transmits an "L (A_B)" frame with destination B, C transmits an "L (C-B)" frame with destination B at the same instant of time t= 0, what can be the maximum length of the frame L (C-B) so that the destination receives it well
