Aim the leftmost Rinka to travel horizontally across the top of the room and use it to damage boost between the two floating platforms. Killing the Rinka will normalize it's respawn timer, which may help in setting up the correct angle. Let the Rinka stay far enough ahead of Samus that she can jump the full distance to the first platform without hitting it. And then once it has reached the right edge of the platform, use it to damage boost.
