Host a sends real time voice to host b over a packet switched network. host a first converts the analogue voice signal to a digital signal at a rate of 64 kbps. host a then creates packets of data where each packet contains 56 bytes. once a packet is created by host a, it is sent to host b over a link that operates at a 2 mbps transmission rate. the propagation delay is 10 milliseconds. (remember to convert bytes to bits). how many seconds does it take to create a packet of data?
