Answer: 12 inches
Step-by-step explanation:
Given that :
Points A, B, C, and D lie on a line consecutively so that AB = BC = CD = 6 in
Therefore, A, B, C and D lie on a line which has a distance of 6 inches between each consecutive point.
A could be taken as the starting point with and D taken the end of the line with B and C in between them.
For instance:
A = 6; B = 12 ; C = 18 ; D = 24
Midpoint of AB = (12 + 6) / 2 = 18/2 = 9
Midpoint of CD = (18 + 24) / 2 = 42/2 = 21
Distance between the Midpoint AB and CD equals:
Midpoint CD - Midpoint AB
(21 - 9) inches = 12 inches
