Use the distance formula: (d=sqrt{(x_2-x_1)^2+(y_2-y_1)^2})
For 3D coordinates, use: (d=sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2})
For speed and time, use: (text{distance}=text{speed}timestext{time})
For a straight line on a map or graph, measure the horizontal and vertical changes first
Subtract the coordinates of the two points
Square each difference
Add the squared values
Take the square root of the sum
Keep units consistent before calculating
Express the final answer in the correct unit, such as meters, kilometers, or miles
