------------------------------------------------ A dog runs 8 m out to fetch a ball and then runs 12 m back towards his owner. If this entire trip took 8 seconds, what was the dog's velocity?

Answer :

Final answer:

The dog's velocity is 2.5 m/s


Explanation:

The dog's velocity can be calculated by dividing the total distance traveled by the total time taken. In this case, the dog runs 8m out and then 12m back, so the total distance is 8m + 12m = 20m. The total time taken is 8s. Therefore, the velocity of the dog is 20m / 8s = 2.5 m/s.
