No, not 250 mph! No airliner has to go that fast to take off.
Take-off speeds in jet airliners are 150-180 mph (250+ kph).
Landing speeds speeds are 120-150 mph.

The rotation speed (speed at the point where the pilot is pulling pack on the controls to raise the nose, increasing the angle of attack of the wings to generate the lift to enable the jet to get airborne.........) will vary greatly from aircraft to aircraft.
Calculating take off speeds require some fairly complex maths - but the main factors that will be taken into account are engine thrust, aircraft mass, and atmospheric & weather conditions.

VR= Velocity Rotation, this is the speed at which the pilot pulls back on the controls and transitions the aircraft from rolling down the runway to flying, on large transport aircraft this speed changes with weight the heavier the aircraft the faster this speed becomes. Some aircraft lower this speed by the use of high lift devices such as flaps and slats and so the exact speed changes with weight and from design to design

Depends on the aircraft and the weather conditions, because airspeed registered on the Airspeed Indicator and the speed the aircraft is actually travelling down the runway (groundspeed)may vary greatly in different conditions.
A typical airliner airspeed at liftoff would be in the region of 160 knots, depending on wing flap/slat configuration and how much the aircraft is loaded down with fuel and passengers.

Me and my ex-partner had a 4 passenger Cessna Skylane. We took off at 70mph and landed at about 60mph. Jet commuters, you are looking at 120+mph, but fuel load, passenger load, and even barametric pressure are all determining factors. When you ask a question like this give all the details, otherwise you will get the wrong answer. (Garbage in, Garbage out), no offense.

It depends on the type of aircraft and the weight of the aircraft at take-off. This typically varies from 120 kts (nautical miles per hour) to 180 kts.

Boeing 747s and large aircraft/'heavies' need about 150 kts.
Smaller - medium sized jets (e.g. A320, 737, 757) need 130 - 140 kts.

Concorde-250mph (before they scrapped it )
B747-400-180/190mph
Airbus-330/340-180mph
Airbus 320/321-160mph
B737-300/400-150mph
Cessna 150-70mph
Learjet/Gulfstream/D-Jet-100mph
Space Shuttle-15,000mph on take off, 25,000mph in the cruise!
Stealth -500mph approx.

you cant tell unless you are in the cook pit. But you can estimate. I would it is determined by the gravity and the weight off the plane. Commercial planes need at least 540 to take off. In the air that will be about 670.
