Please I need help to answer the question in Fundments of Computer Networks.

2. Suppose that Bob sends N back-to-back packets to Alice over two links (shown below), with each link having a transmission rate of R bits/seo. Suppose that the first packet is composed of L bits, the second packet composed of L 1 bits, and so on, with the last packet composed of L+N-1 bits. What is the end-to-end delay of sending all N packets to Alice? Note, consider only the transmission delay that occurs in sending (8 points) packets. Show your work. Bob Alice R bps R bps
