Question: Two rockets are flying in the same direction and are side by side at the instant their retrorockets fire. Rocket A has an initial velocity of +4400 m/s, while rocket B has an initial velocity of +8800 m/s. After a time t both rockets are again side by side, the displacement of each being zero. The acceleration of rocket A is -11 m/s².

Question 1: What is the acceleration of rocket B?

I don't know how to get that answer for above question. Please help.
