Suppose there are 2 routers in sequence between Host A and Host B, all of which use store-and-forward routing. What is the total end-to-end delay for a packet originating from Host A with destination Host B, under the following conditions. Each of the link transmission rates are 3.7 Mbps The total distance from Host A to Host B along its path of transmisison is 171.6 km The speed of propagation through the transmission medium is is 2.7 x 108 m/s The packet size is 3 KiB Remember that you must also uplink from Host A to the first router. Give answer in milliseconds, rounded to 1 decimal place, without units (e.g. for 0.12345 seconds you would enter "123.5" without the quotes).

How do you get to the answer of 20.6?
