Given: S (takeoff run length, distance traveled) = 1215 m; V (the speed of the considered aircraft at the moment of separation from the ground) = 270 km / h (in the SI system V = 75 m / s).
The take-off time of the considered aircraft is expressed from the formula: S = (V + V0) * t / 2 = (V + 0) * t / 2, whence t = 2S / V.
Let’s make a calculation: t = 2 * 1215/75 = 2430/75 = 32.4 s.
Answer: The take-off time of the aircraft in question is 32.4 s.
