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 $9\mathrm{.}4Mbps$

The total distance from Host A to Host B along its path of transmisison is $164\mathrm{.}1km$

The speed of propagation through the transmission medium is is $2\mathrm{.}5{10}^8\frac{m}{s}$

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 $0\mathrm{.}12345$ seconds

you would enter $"123\mathrm{.}5"$ without the quotes$).$
