11.5 km/h

- The girl travels two segments of the journey. First, she covers 30 km at 15 km/h.

- Time for the first segment: 30 km / 15 km/h = 2 hours.

- Next, she covers 20 km at 10 km/h.

- Time for the second segment: 20 km / 10 km/h = 2 hours.

- Total distance: 30 km + 20 km = 50 km.

- Total time: 2 hours + 2 hours = 4 hours.

- Average speed is total distance divided by total time: 50 km / 4 hours = 12.5 km/h.
