need math help

[rudeguy]

Its been a long day and my brain is not hitting on all 3 cylinders.

How long would it take to upload 500 gigs of files if your upload speed is 3Mbps?

I tried figuring it out and I got 3 different answers depending on how I tried to solve it.



Feel free to insult my public education after helping me.

46.29 hours

A long time.

500 GB * 1024 = 512000 MB * 1024 = 524288000 kB * 8 = 4194304000 kb

4194304000/ (3 * 1024) = 1365333.3 s
1365333.3/60 = 22755.6 minutes
22755.6/60 = 379.26 hours
379.26/24 = 15.8 days.

Give or take.

Assumes a 100% sustained upload, so add about 20%.

You need to take the integral of d(xxx)/dt to find the ( . )( . )

Mbps or MBps?

Man I'm tired too. Hope that helped. Good night.

wouldn't you divide the 4194304000 by 3, not multiply?

Mb

Is data transfer ever measured in MB?

 

[brianmanahan]

i suggest you enroll in data comm

I upload at 3MB/s so yeah...

 

[rudeguy]

i suggest you enroll in data comm

I suggest you get me a #2 with cheese, minus tomato and pickle.

nitpick, connection speeds are advertised as powers of 10 so 3 megabits is 3000000 bits. small diff though.

i took data comm so i wouldnt have to do that, lol

Wolfram Alpha is amazing
http://www.wolframalpha.com/input/?i=500GB+at+3+Mbps

edit:
I like some of the random conversions towards the bottom. Light would travel 248.4 billion miles in the time it would take to upload

 

[SKORPI0]

Uploading your pron collection to the cloud servers I presume. ():whiste:

no...a debate I was having at work.

It should read 419430400/ (3*1024), converting the Mbps to kbps. Sorry for the confusion.

Will need to look into that, over here a 3Mbps pipe is also rated at 384 kBps.

384 kBps * 8 = 3072kbps which is the basis I used before using base 2.
