[ee122] HW1: 2b clarification

[Merry Choi]

Some further clarification about the definition of 40ms delay.

Does this mean, say if, a packet could theoretically be sent in 15ms in the
given bandwidth, it would take 40ms for it to actually send? Or rather, this
delay is only applicable to the calculation for the RTT.

?

After you're done acually
If you start counting your wait time after you have received an
acknowledgement, how long have do you actually wait?
