Irodov:Kinematics Q3

Problem: A car starts moving rectilinearly, first with the acceleration w = 5.0 m/s (the initial velocity is zero), then uniformly, and finally, decelerating at the same rate w, comes to a stop. The total time of motion equals = 25s. The average velocity during that time is equal to (v) = 72 km/h. How long does the car move uniformly?
