Solution

a) dprop =  


b) dtrans =  


c) dprop + dtrans =   +  


d) At t=dtrans, the bit would have moved along the link a distance of:
d = S*dtrans
The link distance M is given by:
M = S*dprop
Since dprop > dtrans, the bit will still be on the link going towards the other end of the link.


e) At t = dtrans, the bit would have moved along the link a distance of:
d = S*dtrans
The link distance M is given by:
M = S*dprop
Since dprop < dtrans then M < d, hence the bit would have already reached the other end of the link
