$32$ a$)$ Based on the previous scenario

Suppose Host A is sending a packet to Host B of size L bits. There are two packet switches and three links, with each link s bandwidth equal to $R(\frac{b}{s}).$ Answer the following questions, recalling that the total per node delay is the sum of four different delays. Further assume that each link and processing node $($packet switch or end system$)$ has identical delays. $($a$)$ Assume that $L=1Kb,R=100Mbps,$ the distance between each node is $1,000(km),$ the propagation speed on the link is ${2\mathrm{.}5}^{***}108(\frac{m}{s})$ and the nodal processing delay is $5sec.$ Further, assume that the links are lightly loaded so queuing delay is negligible. Based on the previous scenario, what is the dominant delay component $($i$.$e$.$ which of the delay components is the largest$)?$
