Answer:
To calculate the average velocity of an object, you need to divide the total displacement by the total time taken.
In this case, the object traveled a distance of 1500 m in 50 seconds. So, the average velocity can be calculated as:
Average velocity = Total displacement / Total time
Average velocity = 1500 m / 50 s
Average velocity = 30 m/s
Therefore, the average velocity of the object is 30 meters per second.
