Question

speed and velocity
an object’s speed is a measure of how fast it’s moving. its calculated by measuring the distance the object travels and dividing by the amount of time it takes to travel that distance:
$\text{speed} = \frac{\text{distance}}{\text{time}}$
if an object’s speed is changing throughout the distance measured, like a car speeding up as it gets on the highway, then this equation gives us its average speed during that time.

Explanation:

Since the problem (or the provided content) seems to be just an explanation of speed and velocity without a specific question (like calculating speed for a given distance and time, or a related query), we can't proceed with a solution. If you have a specific question related to speed/velocity (e.g., calculate the speed of a car that travels 150 miles in 2 hours), please provide it so that we can use the step - by - step format to solve it.
