Summary: Speed. Mathematically speed is just distance over time but why? Well think about it from a logical standpoint. Think to produce any level of speed you must be moving. That's were the distance comes in. Distance is the coverage of space. Then we have time which of course we know as the units seconds, minutes, hours, and so on. Now that you know the basics let me show you have to do a Speed equation. For example Sam goes 6 feet in 2 seconds.With this information you can use the formula distance over time equal speed which would mean this equation would be something like 6 feet /2 seconds=3 f/s. So the speed of Sam is 3 feet per second.


S&EP: Using Models:
As you saw in my summary we use mathematics to determine things like speed. Yet we need to put all this math somewhere for it to be more understandable. That's when we meet the graph. With a speed graph we can track speed by the steepness of a slope that line will make. It on the y axis i distance so the line will go as far us as the distance is. Then as for the time it will move as far along the x axis depending on how long it takes to get to the destination. Together those two things make a readable graph that shows those two things.

XCC: Stability and Change:
When it comes to a constant speed its all about stability and an even ratio. For example with Sam's problem we could have the ratio of 3/1 or 6/2 or 12/4 or so on it can scale were the time and the distance stay at an even ratio. Then we can have change when something could accelerate. Acceleration is when there is change to the velocity in this cause speed on either the x or the y axis aka distance or time.That is when you will see a slope like image on a graph because the time and the distance don't line up.
