Walk through deriving a general formula for the distance between two points. The distance between the points ( x 1, y 1) and ( x 2, y 2) is given by the following formula: ( x 2 − x 1) 2 + ( y 2 − y 1) 2. In this article, we're going to derive this formula!

Draw a formula triangle for speed, distance and time. Working clockwise from the top, enter D for distance, T for time and S for speed. Use the formula triangle to work out the correct...
An easy way to remember the formulae is to put distance, speed and time (or the letters D, S and T) into a triangle. The triangles will help you remember these three rules: \(Distance = Speed ...
The equation for calculating distance is \[\mbox{Distance} = \mbox{Speed} \times \mbox{Time},\] but we won't arrive at the correct answer if we just multiply 8 and 45 together, as the answer would be in units of \(\mbox{miles} \times \mbox{minute} / \mbox{hour}\).
Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points. Created by Sal Khan and CK-12 Foundation.
Distance is measured in units of length like meters, kilometers, miles and other units like feet or inches. Time is measured in seconds, minutes and hours. Speed is measured in distance per unit time, for example, meters per second (m/s), kilometers per hour (km/hour), or miles per hour.
Speed is defined as the distance covered per unit time. Speed = (Distance Travelled)/ (Time Taken) Or, S = D/T. Speed also requires a unit of measurement. If the distance is in kilometres.
