What the formula actually models is the average speed of a two legged trip where both legs are identical in distance. Therefore, the magnitude of the object's average velocity is also 0. Scalar And Vector Quantities Average speed is known as a scalar quantity.

In the event that an object travels from point A to point B and back again, the distance that object been displaced is precisely 0 (no matter what units are used to measure). The Average of Two Speeds Average Speed as a Time-Weighted Average T s1/20 + 1/40 s×60/800 s×3/40. The average speed formula can be used to calculate how fast a person must walk to finish a hike by sunset. This is due to velocity being a measure of distance displaced over time rather than distance traveled over time. Using the average speed formula, total distance and elapsed time, the average speed for the entire trip can be calculated as, Note that the average speed is not (50 + 65) / 2 57. Average velocity is commonly calculated by assuming a vertical path, parallel layers. This may surprise you since the average speed on the interval 0,3 was 48 feet/second, yet on the. In geophysics, the depth divided by the traveltime of a wave to that depth. The equation given is only correct if the two legs of the trip exactly the same length in exactly the same direction. Plugging in the values to our average speed formula we get: Which equals 80 feet/second.

To answer Q2 one must first acknowledge the difference between velocity and speed.
