It all depends on the stall speed of the plane this is how they determine the V speeds. On take off you have a rotation speed, or Vr, which is the speed you start to pull back on the controls to lift off the runway, however after you leave the runway the normal climb out speed, or Vy, is much faster. As far as landing goes, the rule of thumb is that the approach speed is twice the stall speed of the aircraft. For example In the 172 stall speed in a landing configuration, or Vso, is 33kts so normal approach speed, or Vref is between 65 and 70kts. However when the plane touches down the speed is much slower, usually around 40kts for the 172.
The approach speed (Vref) is primarily faster than rotation speed (Vr), and primarily slower than normal climb out speed (Vy).

It depends on the particular aircraft you are flying.
The approach & landing speeds are usually set by the manufacturer of the aircraft, & it id determined after extensive flight testing. I fly a Cessna 172 & the normal take off speed is between 70 to 80 knots, & the landing speed is between 60 to 70 knots. But a heavy transport will land & take off at much higher speeds. It all depends on the make, model, & design of the aircraft.

I will come back.
This will depend on the plain(plains Air foil), head wind and the weight (fully loaded or empty).
Jene hand book of plains has this info(not sure about the spelling). Go to library it is on Internet also.
As an engineer I can tel you what is needed.
For landing in fair weather plain has to come at stalling speed plus few knots, stalling speed is the minimum speed at which a plain can barley fly. In bad weather it must come faster then normal.
The takeoff and landings are both done against the wind, or at some angle to the wind. That way if the wind drops all of a sudden or it hits air pocket, the plain will go faster then the stalling speed, it will not fall off the sky, and stay in air.
Experimentally it is proved that most plain loose their steering on dry runway around 85 MPH at this time pilot uses Radder to steer the plain, and keep the plain in the centre of the runway.
The pilot takes the plain up, way above the stalling speed, by taking the plain up slightly first, increasing the speed by applying 90 to 95 % throttle(depends on the plain again.).
Here are some estimated minimum Stalling speed:
Hand glider 10 Knots.
Small plain (Piper Sperrow class) as low as 39 Knots.
Most jets 140 Knots.
Most large Propeler Plains 120 knots.
Large jets Plains 160 Knots.
The stalling speed is tested in the windtunnel and is confirmed by test pilots and then supplied to the trainig/certification instructor.

I have landed as slow as 30 MPH in a 172 due to high headwind which supplies additional lift, and allows for a low ground speed.
Each plane is different, depends on dozens of factors. Weight, temperature, density altitude, engine performance, shape of the wing, upslope or downslope runway, runway condition,

There are several different models of aircraft in use by the airlines and there is a variance between them. You can look up the "pilots opperating handbook" for each model and it will show specific info according to that model. Try: DC 9, MD 80, DC 10, L10-11, 747, 757 as models.

There are many many variables involved with this. Each aircraft has it's own design values for the take-off and landing speeds. Weather, Plane Loading, Altitude of Airport etc... all affect this. You can get help with technical related queries at manufactures websites such as www.boeing.com , www.airbus.com or sites such as www.airliners.net.

Big aircraft land at a MAX of 160 knots no faster and for take off most take off bout 200 knots.
Little aircrafts land at MAX 120 knots no faster and for take off 100 knotts.

7EC Champ will take off at 60 mph. Touchdown is about 40 mph.
Every airplane type is different. Speeds also vary with weight on the same airplane.

for jets , at take off, it is usually 3-400 mph and when landing it is 178-205 mph for emergency landings the bare maximmum is 186

I do not know why but i feel all this depends on the type ,size ,no of engines and the length of the runway etc as such can not be specified.One thing is sure it must be more than 150 KM
