It varies from aircraft to aircraft, and changes with environmental conditons, aircraft configuration, weight, and yes the pilot's mood (and bladder), but generally 'crossing the fence' greater than 120kts.
Speed varies also with different phases of the approach; faster when far out, and stepped down entering the final phases.

I just answered your question regarding the speed that commercial airliners takeoff at. My answer here is fairly similar.
It varies radically depending on an aircraft's weight, the atmospheric conditions at the airfield, and whether an alternate configuration has to be used for some reason.
As a C-5 Galaxy Instructor pilot (a C-5 is slightly larger than a Boeing 747), the slowest approach speed I have ever seen was 115 knots. This is about 132 miles per hour. We were extremely light weight.
The highest approach speed that I have seen was 167 knots which is about 192 miles per hour. We had a flap problem and had to land without flaps. Incidentally, these speeds that I am talking about are indicated airspeed. Our ground speed was somewhat higher than this. The C-5's tire placard speed is 174 knots of ground speed. However, when flying this approach at 167 knots, this was higher than the 174 knots of ground speed. I had to flare the aircraft and wait for the speed to dissipate below 174 knots ground speed before I could touch down.

The CRJ-200 comes in at 146 kts or 168 mph at 47,000 pounds (our max landing weight, we can takeoff weighing 53,000 lbs) with flaps set at 40 degrees this speed varies with our weight and flaps setting wind conditions also play a small role as well. The general rule is the larger and heavier the aircraft the faster the approach speed.

I've landed between 120mph and 310mph. Anywhere in between is fine. It depends on windspeed and the amount of flaps you are using. You need more runway at the higher speeds and extra reverse thrust.
If you lose a wheel, or suck a bird, then you're in trouble. I had 2 wheels blow and birds got sucked all at once coming in at 235mph. That one was hairy. And don't call me Shirley.

Hopefully at landing speed!

it all depends on th size and weight of the plane

That would depend on the mood of the pilot....

maybe about 200km/h ??
