Problem
Estimate the time it takes to send 
blocks of data over a communications channel if each block consists of 
"chunks" and the channel can transmit 
chunks per second.
Solution
We want to figure out the number of chunks in blocks, so we have 
. We divide this by to determine the number of seconds necessary to transmit. 
, which means that it takes approximately 
minutes to transmit. Thus, the answer is 
.
