How long would this download take?

I want to make sure I get the maths on this totally correct
say you have a 24 mb/s connection (and got all of that)
How long would it take (in theory) to download a full 4GB of data ? (in seconds)
Just wondering cos I've seen an ISP with that speed but also that teenyweeny monthly download limit

Ah yes, but he said:
Mind you, to get a server to upload that fast you would need to open multiple connections simultaneously via a download manager or something. And apart from major ones, most servers probably have less than that upload as their maximum capacity!
Torrent is the way to go, for all files I think. (well, splitting files into small chunks and having lots of people seeding / distributing) A world wide hub of data, where you can get any data you want from everyone, there are no limits except what you can download at then.
Wow, my 4 megabit at home could download at up to 480kb/s, which I thought was fast!
Not to sound like a school teacher but can you show your workings out .. lol
so 24 megabits / second = 3 megabytes per second
1 gigabyte = 1024 megabytes
so, 4 gigabytes = 4096 megabytes
4096 / 3 = 1365.33 seconds
= 22.75 minutes = 22 minutes, 45.33 seconds
I have to disagree with this...
All of this is academic really. I presume this is LLU ADSL2+ provider in which case you'll never sync at 24meg. Also there is TCP/IP overheads which is about -5%.
24Mb = 2.861MB per second(or 171.66MB per minute)
4096MB / 2.861MB = 1431.67 seconds
1431.67 / 60 seconds = 23.86 minutes
.86 * 60 seconds = 51.6 seconds
Total time, assuming perfect connection and maximum throughput, no overheads, etc = 23 minutes, 51.6 seconds
~25 minutes would be a fair time on a perfect connection. Real world is likely to be a tad longer - especially if the speed isn't at maximum.
What happens is that adsl2+ or whatever has the capacity to run up to that, but in order to receive it you have to be within 100m of the exchange. Only 15% of the population are within 1km of an exchange, and it said maximum speeds of 18Mb were far more likely...
