Consider a car initially at rest, starts to move along a straight road first with acceleration 5 m/s2, then with uniform velocity and finally, decelerating at 5 m/s2, before coming to a stop. Total time taken from start to end is t = 25 s. If the average velocity during that time is 72 km/hr, the car moved with uniform velocity for a time of
