8. We have two hosts, host A and B connected by a single link of rate R bps. The distance between the hosts is m meters and the propagation speed on the link between them is s meters/sec. Host A attempts to send a packet of size L to host B.

   a- What will be the propagation delay, d_prop , in terms of m and s.

   b- What will be the transmission time d_trans , in terms of L and R.

   c- If you ignore other types of delay, what will be the total delay?

   d- If host A starts to transmit the packet at t = 0, where will be the last bit of packet at time t = d_trans

   e- If d_prop < d_trans , at time t = d_trans where will be the first bit of the packet?

   f- Assume that s = 2.5*10^8 , L = 100 bits, R = 28 kbps. What is the distance m if d_prop = d_trans.
