It depends a great deal on the airplane, how heavily it is loaded, and other factors.
Jets will usually cover 30 miles in only a few minutes. They are often already traveling at 3 miles per minute shortly after leaving the runway, and accelerate to 4 miles per minute or so very quickly, so that's only 8-10 minutes to cover 30 miles.
Cruise altitudes vary. Some airplanes will climb to or beyond 30,000 feet for cruising, but others may not climb that high, especially on short flights. It may take 8-20 minutes to reach cruising altitude, again depending on many things. During that time, a jet might cover 40-100 miles.
At 30 miles from landing, most big airliners have already descended to a much lower altitude than their cruise altitudes. They might be at 10,000 feet or so, but this depends on a great many things. It's very unlikely that they'll still be at cruise altitude, because airliners glide into their destinations with engines mostly idle, and in order to glide down from typical cruise altitudes, they need to start about 80-100 miles out from their destination airports.
Well unfortunantly it completely depends on the airplane type you are in and how heavy it is. Generally by 30K I have covered 80 miles or so in a CRJ 200. 30 miles from the airport it can range from 3000 feet to about 10,000 just depending on the airport, traffic in the area and the arrival procedure.
