Consider the figure below. Two packets each with size of 10k bits are to be transmitted from the source (the left-most device) to the destination (the right-most device) along the 3-link path. The data transmission rates of the links 1,2 and 3 are 5Mbps,2Mbps, and 1Mbps, respectively. The physical distances of links 1,2 , and 3 are 2km,5km, and 1km, respectively. The signal propagation speed is 2105 km per second. What is the minimum amount of time needed to transmit the two packets end-toend? 17ms27ms25ms34ms
