Given:  A dog runs directly from point A to point B at a rate of 20 feet/second. The dog then runs directly from point B back to point A at a rate of 17 feet/second.

Problem:  Determine the average velocity of the dog as it traveled this path.

Definition:  Average velocity is calculated by taking the total distance traveled and dividing it by the total time traveled.

Hint:  The solution is not (20 + 17) ÷ 2 or 18.5 feet/second.

Result:  The average velocity of the dog is feet/second. Round your solution to the nearest tenth of a foot/second.
