For this question, let the packet size L $=1000$ bytes, the propagation speed s $=2\mathrm{.}5$ x $108$ m$/$s$,$ the

link distance d $=2000$ km$,$ and the transmission rate R $=10$ Mbps $($megabits per second$).$ Assume

that $1$ Mbyte $($megabyte$)=1$ x $106$ bytes $($SI definition$).$ Be mindful of units. Answer these

questions
