In physics, escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a massive body. The escape velocity from earth is about 40,270 km/h (25,020 mph).
What about the average speed according to definition 1? In this case, the distance traveled is 1000 meter so that the average speed would be (1000 m)/(50 s) = 20 m/s. This is what the speedometer would read. According to definition number 2, the average speed is the magnitude of the average velocity. Since the average velocity is zero (vector) m/s, the magnitude of this is also zero meters per second. If you want the instantaneous speed according to the definition 2, that would also be 20 m/s.
