@Harendra.
Here, we can use a quadratic equation.

Here the angle of projection is also from horizontal.

S= ut + 0.5 a (t)^2.
here S=0, since range is horizontal distance covered until the particle reached the its initial point.
overall angle of projection = (α-β).
accelaration (a) = g*cosβ , since inclination of the plane is present.
u = intial velocity in x direction = usin(α-β).
Substitute all the values in the equation. You will get the answer.

According to me, the answer is (2ucos(a))/(gcos(b)).

Rotate your coordinate axis by beta degrees and resolve your "g" component in your new axis.
Your displacement in y-axis will be given as.
y = usin (a-b) - 0.5cos (b) t^2.
After a time of flight T displacement along y-axis will be zero places y = 0 in the equation, you will get the answer.

The total time taken by a projectile to reach the maximum height and to return back to ground is known as the time of flight.

@K.Kisku.
While throwing an object, the time taken by the object to reach rest or destination.
