You cannot.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.
If you are only given total distance and total time you cannot. If you are given distance as a function of time, then the first derivative of distance with respect to time, ds/dt, gives the velocity. Evaluate this function at t = 0 for initial velocity. The second derivative, d2s/dt2 gives the acceleration as a function of time.
Get the value of initial velocity. Get the angle of projection. Break initial velocity into components along x and y axis. Apply the equation of motion .
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
You can only know the distance for sure if acceleration or deceleration is constant. Add the start and end velocities and divide by two and then multiply by the time to get your distance.

If you take initial velocity(Vi) to be zero and the final velocity (Vo) to be a known. Puting the knowns into a triganonomical equation and solving for the value of D would give an answer
Use the formula Acceleration = (final velosity - initial velocity)/ time.
You cannot.
