Question $8$

Suppose in Question $1$ the packet is $1,500$ bytes, the propagation speed on all

three links is $2\mathrm{.}5{10}^8\frac{m}{s},$ the transmission rates of all three links are $2\mathrm{.}5$

Mbps$,$ the packet switch processing delay is $3ms,$ the length of the first link is

$5,000km,$ the length of the second link is $4,000km,$ and the length of the last

link is $1,000km.$ For these values, what is the end$-$to$-$end delay to the nearest

millisecond?

Notice that $1,500$ bytes is in bytes, not bits. Also, watch out that the

distances are in $km$ rather than $m.$
