How long does it take to send a $2$MiB file from Host A to Host B over a circuit$-$switched network, assuming:

Total link transmission rate $=28\mathrm{.}8Gbps.$

Network is TDM$,$ with $8$ permitted users, each with an equal time slot size.

A link connection requires a setup time of $76\mathrm{.}4ms.$

Your answer should be in miliseconds $($ms$)$ with one decimal place, and without the unit $($e$.$g$."140\mathrm{.}6"$ without the quotes$)$
