I'm not a pilot but fly a a lot as a passenger for work. A 30k ft decent in 10 mins while fast, doesn't seem extreme. Now I'm sure if you heard a sound and the captain comes on to tell you that an emergency landing needed to take place, it would feel like an eternity and be scary as heck. Glad everyone was safe in the end.
If I had to WAG, probably 800 or so feet per minute faster than normal up high and 1500 or so feet per minute faster down low.
Most airline type flying is a 3 degree descent or 300 feet per mile.
So 2100-2400 feet a minute at Mach .7-.8 and 1000-1200 feet per minute down low at 250 KIAS
