Answer:
62.5Km/h
Step-by-step explanation:
To calculate the magnitude of the bus' average velocity, we divide the total distance traveled (1250 km) by the total time taken (20 hours). Therefore, the magnitude of the bus' average velocity is 62.5 km/h. This means that, on average, the bus covered a distance of 62.5 kilometers in one hour. It's important to note that velocity is a vector quantity and includes both magnitude (speed) and direction. However, since the question only asks for the magnitude of the average velocity, we consider only the speed component.
