... When expanded we see that there are 11 terms. (We could also get this directly as ⌈log2 1561⌉.) This means that the total amount of time to send the file is the initial handshake, plus the 11 RTTs to send the groups, plus a final one-way propagation for the last group to reach the destination: 0.08 ...
