Cоnsider twо hоsts, A аnd B, connected by а single link of rаte 1 Mbps. Suppose that the two hosts are separated by 3,000 Km, and suppose the propagation speed along the link is 3x108 m/s. Host A is to send a packet of 1,000 bytes to Host B. Calculate the propagation delay in seconds. (Hint: dprop = d / s)
