What is the distance formula?

Answer 1

If you want the distance between two points on a graph, the formula goes as follows

d = sqrt ( (y2 - y1)^2 + (x2 - x1)^2 )

where (x1,y1) and (x2, y2) are the points in question.

Side topic, if you wanted to find the midpoint of those two points, it will be:

[ (x1+x2)/2 , (y1+y2)/2 ]

Answer 2

There are two general formulas:
Case A: Horizontal movement, like a car travelling from point A to point B with a constant velocity (or speed).
d = r x t
Where
d = distance
r = rate
t = time
Case B: Vertical movement, like a football drop from a window of a second floor of the house to the ground with a constant acceleration.
x = x(sub o) + v(sub o) x t + 1/2 x a x t (squared)
Where
x = distance after the football accelerates for a time, t
x(sub o) = initial distance
v (sub o) = initial velocity
a = acceleration
t = time

Answer 3

If you want to find the distance between two real numbers x and y, the formula is

|x - y|

If you want to find the distance between two points in the plane (x1, y1) and (x2, y2), the formula is

√((x2 - x1)^2 + (y2 - y1)^2).

If you want to find the distance between two points in space (x1, y1, z1) and (x2, y2, z2), the formula is

√((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2)

Answer 4

d=rt. Or distance= rate x time

Answer 5

d=sqrt "(x2-x1)^2 + (y2-y1)^2"

Answer 6

t(time)*r(rate)=D(distance)

Answer 7

D = R[ate] X T[ime]
