9. A male and female track and field athlete are practicing running on a 110-meter slope (the top of the slope is $\mathrm{A}$, the bottom is B). Both start from point A at the same time, running back and forth between A and B continuously. If the male athlete's uphill speed is 3 meters per second, and downhill speed is 5 meters per second; the female athlete's uphill speed is 2 meters per second, and downhill speed is 3 meters per second, then the location of their second face-to-face meeting is $\qquad$ meters away from $\mathrm{A}$.
