Consider two packet switches directly connected by a link of 4000 km, propagation speed 2 x 108 m/s (read as 10 to the power of 8), and transmission rate 5 Mbps. (4 points)

How long does it take to move a packet of length 5,000 bytes from one packet switch to

the other packet switch? (2 points)

Generalizing the above, how long does it take to move a packet of length L over a link of distance d, propagation speed s, and transmission rate R bps? (2 points)
