Good points. The 30% increase and the not-straight-distance could explain a 50% slowdown. But here we have a 500% difference.

Also the number of hops probably isn't really relevant : there probably isn't any router in the middle of the Atlantic, and just like you said there is already a bunch of router on an European-only route whose latency would most likely be below 10ms.

It's not really a question of where the hops are located. There'll be a couple of them in Europe and a couple in NA. Each will introduce a bit of latency.

The numbers from the article are also round-trip times (that's what you get with the ping command), so you'd have to double whatever number you come up with from the one-way distance alone.

Indeed, the theoretical minimum ping time for 9000km is 60ms.
