Considering Figure, the data rate is 10Mbps, the distance between station A and C is 2500m, and propagation speed is 2 x 108m/s. Station A starts sending a long frame at time t = 0; station starts sending a long frame at time tz = 3us. The size of the frame is long enough to guarantee the detection of collision by both stations. Find i. The time when station Chears the collision (tz) ii. The time when station A hears the collision (ta) iii. The number of bits station A has sent before detecting the collision. The number of bits station C has sent before detecting the collision. iv
