Question

dont dont dont answer without 100% sure strict warning strcitly saying skip if u dont know 

Two endpoints are connected by a single link of rate R = 56kbps and the propagation speed along the link is 2* 10^8.
a) If one wants to send a packet of 120 bits to the other, what is the distance m so that the propagation time equals the
transmission time?
b) Suppose the server begins to transmit the packet at time te0. when t= transmission delay, where is the last bit of the packet?
c) If the propagation time were greater than the transmission delay, where is the first bit of the packet when time is equal to the
transmission delay?
d) If the propagation time were less than the transmission delay, where is the first bit of the packet when time is equal to the
transmission delay?
