The car covered 60 km per hour. Can it be argued that his movement was uniform?

1) If a given car traveled for equal intervals of time (1 hour) the same distance (60 kilometers) and its speed at each such section was constant (V = const), then the movement will be uniform.

2) In the event that each section of 60 km, a given car was moving not at a constant, but at an average speed of 60 km / h (30 minutes at a speed of 120 km / h and 30 minutes at a speed of 0 km / h, etc. ), then such a motion will not be uniform (V ≠ const).
