Voice over IP (VoIP)

Given the attached image, and:h

• Host A converts analog to digital at a = 33 Kbps
• Link transmission rate R = 3.4 Mbps
• Host A groups data into packets of length L = 83 bytes
• Distance to travel d = 630.8 km
• Propagation speed s = 2.5 x 10⁸ m/s
• Host A sends each packet to Host B as soon as it gathers a whole packet.
• Host B converts back from digital to analog as soon as it receives a whole packet.

How much time elapses from when the first bit starts to be created until the conversion back to analog begins? Give answer in milliseconds (ms) to two decimal places, normal rounding, without units (e.g. 1.5623 ms would be entered as "1.56" without the quotes) Correct answer is 22.84 please show steps.
