Difficulty—

A, B, C, D and E are 5 consecutive points on a straight line. If BC = 2CD, DE = 4, AB = 5 and AC = 11, what is the length of AE?

A. 21.
B. 26.
C. 30.
D. 18.

The OA is the option D.

How can I find the total length? What are the equations that help me to solve this PS question? I need some help.!!! <i class="em em-neutral_face"></i>
