Final answer:
The average speed of the basketball rolling down the hill is 12 m/s.
Step-by-step explanation:
The average speed of an object is calculated by dividing the total distance traveled by the total time taken. In this case, the basketball rolled 300 meters down the hill in 25 seconds. To find the average speed, we divide 300 meters by 25 seconds:
Average Speed = Distance/Time = 300 meters / 25 seconds = 12 meters per second (m/s)
Therefore, the average speed down the hill is 12 m/s.
