Yes, the scooter can be accelerating even when its speed remains constant. This happens when its direction of motion changes, such as while moving along a circular path. Acceleration changes velocity, not necessarily speed.
A girl is riding her scooter and finds that its speedometer reading is constant. Is it possible for her scooter to be accelerating and if so, how?

Yes, it is possible for the scooter to be accelerating even when its speedometer reading remains constant. Acceleration is the rate of change of velocity and velocity depends on both speed and direction. Therefore, if the scooter moves with constant speed but continuously changes its direction, its velocity changes and the scooter is accelerating. For example, this occurs when the scooter moves along a circular path.
