To find the distance between two points we will use the distance formula: √ [ (x₂ - x₁)² + (y₂ - y₁)²]: Get the coordinates of both points in space. Subtract the x-coordinates of one point from the other, same for the y components. Square both results separately. Sum the values you got in the previous step.

Distance, often assigned the variable
, is a measure of the space contained by a straight line between two points.
Distance can refer to the space between two stationary points (for instance, a person's height is the distance from the bottom of his or her feet to the top of his or her head) or can refer to the space between the current position of a moving object and its starting location. Most distance problems can be solved with the equations
where d is distance, s
is average speed, and t is time, or using
d = √ ( (x
Find values for average speed and time.
When you try to find the distance a moving object has traveled, two pieces of information are vital for making this calculation: its
(or velocity magnitude) and the
that it has been moving.
With this information, it's possible to find the distance the object has traveled using the formula d = s
To better understand the process of using the distance formula, let's solve an example problem in this section. Let's say that we're barreling down the road at 120 miles per hour (about 193 km per hour) and we want to know how far we will travel in half an hour. Using
Find two points spatial coordinates.
What if, rather than finding the distance that a moving object has traveled, you need to find the distance between two stationary objects? In cases like this, the speed-based distance formula described above won't be of any use. Luckily, a separate distance formula
can be used to easily find the straight-line distance between two points. However, to use this formula, you'll need to know the coordinates of your two points. If you're dealing with one-dimensional distance (such as on a number line), your coordinates will be two numbers, x
If you're dealing with distance in two dimensions, you'll need values for two (x,y) points, (x
). Finally, for three dimensions, you'll need values for (x
Find 1-D distance by subtracting the value of the coordinates for the two points.
What is the formula for finding the distance traveled of a moving object?
Distance traveled = rate (velocity) multiplied by time elapsed. D = (v) (t).

Jun 14, 2023 · Solve the formula by squaring the differences of the x and y values, adding these differences together, and finding the square root of the remaining sum. Take the coordinates of two points you want to find the distance between. Call one point Point 1 (x1,y1) and make the other Point 2 (x2,y2).
The distance formula is $ \text{ Distance } = \sqrt{(x_2 -x_1)^2 + (y_2- y_1)^2} $ Below is a diagram of the distance formula applied to a picture of a line segment Video Tutorial on the Distance Formula
To find the distance between two points, simply follow these steps: Find the XY coordinates of the first point (x₁, y₁). It doesn't matter which point we choose as long as we don't mix coordinates between them. Find the XY coordinates of the other point (x₂, y₂). √ [ (x₂ - x₁)² + (y₂ - y₁)²].
Jun 27, 2024 · How to Find the Distance Between Two Points. The first point and second points on your graph will each have an x coordinate and a y coordinate. You can calculate the shortest distance between these two points by using the Euclidean distance formula, which is a Pythagorean theorem-related algebraic expression. D = √ (x₂ - x₁) ² + (y₂ ...
