Answer:

12 miles per hour

Step-by-step explanation:

Speed is the ratio of distance travelled to the time used.

The total distance covered = (5 + 13) miles

                                             = 18 miles

The whole journey took 1 hour + 30 minutes = 1.5 hours

                    Average rate of speed = \frac{total distance covered}{total time taken}

                                                           = \frac{18 miles}{1.5 hours}

                                                           = 12 miles per hour

Therefore, her average rate of speed is 12 miles per hour.
