General Math Question

Hi Guys,

I simply wanted to ask, I have a large file that I want to download the size of 4,375,272 at the speed of 160kb/sec. How can i find out how long it will take in HH:MM:SS?

I have tried the following:
$a = 4,375,272
$b = 160kb/sec

$totalsecs = $a * $b = 700043520
$totalmins =$totalsecs / 60 = 11667392
... not sure where to go from here?
Can somebody help me find a way for me to find out how long it will tak to download?

Let t be the download time. Assuming the file size is in bytes:

Re: General Math Question

total bytes = (bytes per time)(total time)

thus:

total time = (total bytes)/(bytes per time)

It is mathematically equivalent to asking how long will it take to travel a certain distance at a certain speed:

time = distance/speed
