No, that's 5Mbps. Since you always see on adverts "up to 8Mbps", this sounds about right, it's a good but fairly average home internet connection in the UK.
5Gbps is about 1000x faster.
(I've just done the test and get 55284kbps, both upload and download. Lovely!)
So, let's do some quick maths.
Your connection is apparently 5584kbps.
Your file is 60MB. Converting this to kb --> 480,000kb.
(I just multiplied by 8,000 to convert from Mega to kilo, and from Bytes to bits.)
So, do 480000 / 5584, which will tell you how long it should take it seconds.
This comes to 86 seconds. A little over a minute.
If you allow for extra losses, you could multiply your speed (5584) by 0.7, to get 70% of that speed. (30% losses seems a lot perhaps, but it tends to be a pretty good real world value.) Even with this, it still just comes to 122 seconds. 2 minutes.
So 10 minutes is far slower than your connection should be, assuming that you can download to the maximum your connection supports, even taking into account losses.
It's here that kempie and gen2's answers become the issue. This is why your download is slow.
Try going to speedtest.net again, and running the test from a server in the US or Australia. Different speeds? It's going through far more networks and servers, so you get more losses.
