Two identical particles, each of mass 1400 kg, are coasting in free space along the same path. At one instant their separation is 30.0 m and each has precisely the same velocity of 820 m/s. What are their velocities when they are 4.00 m apart?

I know! but that's the exact homework question I have. I think it means that at that instant (when they're 30 ft apart) they have the same velocity. But mass 2 is gaining on mass 1. But I could be mistaken.
