Homework Statement
Galaxy A moves away from galaxy B at 0.650 c0 relative to B. A spaceship leaves a planet in galaxy A traveling at 0.550 c0 relative to galaxy A. If the direction in which the ship travels is the same as the direction in which A is moving away from B, what do observers in B measure for the ship's speed?

The Attempt at a Solution
I thought that the speed would be .550c , but this appears to be incorrect. Any thoughts?
