Suppose there are 3 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 2.1 mbps the total distance from host a to host b along its path of transmission is 130.4 km the speed of propagation through the transmission medium is is 2.5 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).
