The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2.

Speed Calculator Or, if you have your pace, you can convert it to speed. Simply divide 60 by your pace. When you aren’t using whole hours in the calculation, convert the number to minutes, then multiply the result by 60 minutes per hour to get miles per hour or kilometers per hour.

Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour.

approximately 0.6818 miles per hour. exactly 1.09728 km per hour.

You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

The formula for distance problems is: distance = rate × time or d = r × t. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.

A General Note: Rate of Change The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

Slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. If coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

In math, slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . This simple equation is called the slope formula.

A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

y=3 would be nothing more than a horizontal line through y=3. So the rise is always 0 (it never goes up or down) and the run is always the distance from zero to any point on the line. In other words, the slope would be 0/the change in x, which is always 0.

Using the slope-intercept form, the slope is 4 .

zero

The slope is 0 and the y-intercept is -4.

Using the slope-intercept form, the y-intercept is 0 .

The letter m is your slope, and the letter b is your y-intercept. So, looking at your line’s equation, we have y = 1/3x – 2. With this being said, 1/3 is your slope, and -2 is your y-intercept.

Using the slope-intercept form, the y-intercept is −3 .
