Consider sending real-time data from Host A to Host B over a packet-switched network. Host A takes a 32-bit measurement every millisecond, and Host A collects these into 128-byte packets. There is one link between Hosts A and B; its transmission rate is 2 Mbps, its propagation delay is 2 10⁸ meters/sec, and its length is 1500 km. As soon as Host A gathers a packet, it sends the packet to Host B. How much time elapses from the time that Host A begins to take the first measurement in a packet until the packet reaches Host B?

Please help me understand what seems like it should be a simple solution.
