Calculate the total time to transmit a 1500 KB file over a link. Assuming the one way delay in either direction is 40ms, and an initial RTT of “handshaking” before any data is sent.(Note: 1 KB = 210 bytes, 1 Mbps = 106 bits/s). The bandwidth is 1 Mbps, the packet size including the header is 1 KB of which the header is 40 bytes, and the data packets are sent continuously and never lost
