Constant does not mean zero, it means it doesn't change with time. That is, the acceleration is the same for the entire 15 seconds.

vf^2 = vi^2 + 2a(delta x)

22.22^2 = 11.11^2 + 2a(250)

Is this the right way to find a?

The problem is that you used 16.67 m/s in post #23, that is the average velocity, you need to use the change in velocity.

Acceleration = Change in velocity / change in time

a = 11.11 m/s / 15 s

a = 0.74 m/s^2 ?

a = 0.74 m/s^2 ?
