Problem $)=(20pts.$ You set up a communication channel between two medieval castles by letting a trained raven repeatedly carry a scroll from the sending castle to the receiving castle, $200$ kilometers away. The raven flies at an average speed of $40k\frac{m}{h},$ and carries one scroll at a time. Each scroll contains $1\mathrm{.}8$ terabytes $($TB$)$ of data. Calculate the average data rate $($in bits per second, or bps$)$ of this channel when sending

$1\mathrm{.}8$ terabytes of data

$3\mathrm{.}6$ terabytes of data

an infinite supply of data $($i$.$e$.,$ the raven works non$-$stop to eternity$)$

$(*$use $1TB={10}^{3}GB={10}^{12}B,$ and $1B=8b)$
