I now what Are the answers of c and e but could you please only explain how we get these answers? thanks

Initially this router is also connected to two routers, each over a 50Mbps link with a 200ms propagation delay. A 1Gbps link connects a host and a cache (if present) to each of these routers and we assume that this link has 0 propagation delay. All packets in the network are 20,000 bits long. Again we assume only one active client but in this case the caches are on and behave like HTTP caches. A client's HTTP GET is always first directed to its local cache, 60% of the requests can be satisfied by the local cache. What is the average rate at which the client can receive data in this case? Answer: We assume that requests are serially satisfied. 40% of the requests can be delivered at 25Mbps and 60% at 1 Gbps. So the average rate is 10Mbps. is al har reale client be satis 1 Now consider Figure 2 where the network has been extended by two additional LANs, which are connected via 25Mbps links and the throughput of the server link is only BOMbps. In all four LANS 60% of the requests can be satisfied by the local enches. What is the average rate at which each client can receive data? Answerz Now the server link is the bottleneck link an equally shared by all clients, each getting 20Mbps. 3096 of the client requests are served at 20Mbps and 0096 of the requests are delivered at 1Gbps, Penning in an average rate of GOBMbps. On a reduction by 2 Mbps on average despite a 50% reduction in server link bandwidth. This show how efficient cach can be
