I have a 5Mbs connection and I am downloading some 50MB files.

D=RT T=D\R 50MB/5Mbs = 50/5(8) = 50/40 = 1.25s

I know this is not right because the files takes about 3 min each.

Is my math wrong, or is my computer connection much slower than
advertised, or both?

What should be my true speed? What is my actual speed?

Mb = Megabits and is in terms of bits(8bits = 1 byte)
MB = MegaBytes and is in terms of bytes.

so

50MB * 8bits/1byte * 1s/5Mb = 80s

(technically its 50*10^6 Bytes * 8 Bits/1 Byte * 1s/5*10^6 Bits)

As others have mentioned, you will rarely even get close to using your whole
bandwidth. In some cases you might actually "exceed" it if the file is
compressible.
