V) Transmission Time and Propagation Delay (21 POINTS) 1) Consider a point-to-point link 50 km in length. At what bandwidth would propagation delay (at a speed of 2 x 10 m/s) equal transmission delay for: n. 100-byte frames. b, 512-byte frames. 2) a) How "wide" is a bit on a 10 Mbps link? b) How long is a bit in copper wire, where the speed of propagation is 2.3 x 10' m/s? 3) How long does it take to transmit X-KB over a y-Mbpslink? Give your answer as a ratio of and y
