Why is a ping pong ball pulled toward running water?
Running water moves the air next to it. Moving air has less pressure than air that is still. This is the Bernoulli principle, and helps airplanes to fly. With less pressure on one side from moving air, and more pressure on the other side from still air, the ping-pong ball moves towards the water.

What is an object's total distance traveled divided by the total time it travels?
In general, we will find the average speed of a moving object by dividing the total distance it travels by the total time elapsed in its travel.We can find the actual speed of the object if it moves with a constant speed during all of its travel. But if the object is something like a bus or train that makes stops along the way, we discover its average speed by dividing the total distance it travels by the total time it took to travel that distance.

There is no such a thing as "average cost of moving". Every household is different, that means every move is different. Local moves within a state charged by hourly rates, the total amount is calculated based on the number of movers and hours worked. This is different from the weight based system used for out of state moves.
