It’s AB and DE so it would be b

The correct answer to this question is b) AB & DE.

The two intervals represent equal displacement of the particle. Delta (x) is always 2. So you need to, average the initial and final velocities of each interval. Then to find total displacement, multiply by two.

2 * [ (0 + 10)/2 ] = 10 for interval AB
2 * [ (7 + 3)/2 ] = 10 for interval DE

Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
