Suppose that Alice wants to send Bob a 50 kilobyte message over a 1 Gbps link. The total time required to transmit the message (i. e., message latency) is 2 milliseconds. What is the throughput of the connection? Express your answer in Mbps rounded to the nearest whole number, and leave off the units. For example if the answer is 857.7823 Mbps, fill your answer in as 858
