Speed is a continuous variable since it can take on an infinite set of values.
Each of those is better in some situations. Also, you often have no choice. Some quantities, like speed and temperature, are inherently continuous, whereas some quantities, like the number of girls, cars, or beans, are inherently discrete.
A parameter is a limit: could be a speed limit on the road. A variable is something that changes in the system: could be the actual speed of a car.
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
The average wind speed in Great Falls, MT, is 2.7 miles per hour greater than that in Chicago, IL. This is calculated by subtracting Chicago's average wind speed of 10.4 mph from Great Falls' 13.1 mph. Therefore, Great Falls experiences a noticeably higher average wind speed.
13.1/10.4 = 1.26 that is Great Fallls is 26% greater wind speed than Chicago
No, it is a continuous variable.
Usually we consider a random variable which assigns a value to the outcome of an event. The value assigned to the outcome can be either discrete or continuous. The continuous random variable is a random variable whose domain is defined over a continuous range. Examples: Daily inches of rain, speed of cars on highway, purchases made everyday at grocery stores.

The speed of a car is considered a continuous variable. It can take on any value within a certain range, meaning it can vary smoothly without gaps. For example, a car's speed can be 30.5 mph, 30.55 mph, or any other fraction within the limits set by its maximum speed. Thus, it is not limited to specific, separate values.
The distance a baseball travels in the air after being hit is considered a continuous variable. This is because it can take on any value within a range, depending on factors such as the angle of the hit, speed, and environmental conditions. Unlike discrete variables, which consist of distinct, separate values, the distance can vary smoothly and can be measured with great precision.
You age, your height, your mass, the speed at which you run, the energy you burn in doing so. They may be measured as discrete quantities but the underlying variables are all continuous.
Variable motion refers to motion that is not constant, but changes in speed and/or direction over time. This could include acceleration, deceleration, or changes in velocity during an object's movement.

It is not necessarily a motion in itself... Variable speed refers to something that can change speeds, or that the speeds can be changed. There are many things that can be variable speed.
time = distance/speed time = 1676/60 = 27.9 hours, or about 28 hours of continuous driving at that speed
Dependent variable is usually speed.
