If a vehicle travels 150 km in 3 hours, what is its average speed?

To determine the average speed of a vehicle, you divide the total distance traveled by the total time taken. In this case, the vehicle travels 150 kilometers over a period of 3 hours. By performing the calculation:

Average Speed = Total Distance / Total Time

Average Speed = 150 km / 3 h

Average Speed = 50 km/h

This calculation shows that the average speed of the vehicle is indeed 50 km/h.

The term "average velocity" can sometimes introduce confusion; however, when we refer to average velocity in this context, it's important to note that average speed and average velocity can be considered equivalent when discussing magnitudes, especially in a straight-line motion without changes in direction. Thus, stating the average velocity of 50 km/h accurately reflects the average speed.

While the other options mention relative velocity or simply note that a distance of 50 km was covered, these do not correctly describe the situation, as relative velocity has a specific meaning often involving the motion of one object in relation to another, and stating a distance of 50 km is inaccurate as the vehicle covers a total of 150 km.
