Ok, I have this problem :(adsbygoogle = window.adsbygoogle || []).push({});

------A device for training astronauts and jet fighter pilots is designed to rotate the trainee in a horizontal circle of radius 10.3m. If the force felt by the trainee is 7.15 times her own weight, how fast is she rotating? -------

I already calculated that she is rotating 26.9 m/s. But now they are asking me to calculate my answer in revolutions per second. I tried using

{2 * Pi * radius} / velocity = rpm....but I think I'm doing it wrong, since the answer wont come out right. I know that equation solves for revolutions per minute and I'm supposed to solve for revolutions per second, but I tried to multiply by 60 and it still doesn't work. Anyway, if anyone sees what I'm doing wrong, could you please tell me how to fix it and convert to rps? Thanks so much.
