Consider two hosts, A and $B,$ connected by a single link of rate $R$ bps$.$ Host A sends a packet of size $L$ to Host B$.$ Suppose $d_{\text{p}\text{r}\text{o}\text{p}}$ is greater than $d_{\text{t}\text{r}\text{a}\text{n}\text{s}}.$ At time $t=d_{\text{t}\text{r}\text{a}\text{n}\text{s}\text{,}}$ the first bit of the packet is
