A $64000-byte$ message is to be transmitted over a $2-hop$ path in a store- and-forward packet-switching network. The network limits packets to a maximum size of $2032 bytes$ including a $32-byte$ header. The trans- mission lines in the network are error-free and have a speed of $50 Mbps$. Each hop is $1000 km$ long and the signal propagates at the speed of light $(3 \times 10^8$ $\text{meters per second)}$. Assume that queuing and processing delays at the intermediate node are negligible. How long does it take to deliver the entire message from the source to the destination?
