The average speed of Dolly is 33.33kmph.
Average Speed:
The average speed is defined as the total distance travelled by the object in a particular interval of time. It can be calculated by dividing the total distance travelled by the total time taken.
So, Average Speed = total distance / total time
Here,
Let the total distance is 100 km.
Therefore, consider she will travel 60 km at speed of 60 kmph , 30 km at speed of 30 kmph and 10 km at speed of 10 kmph.
she will required times of 1 hour, 1hour and 1hour

Average speed = 100 / (1 + 1 + 1)
=> 100 / 3 = 33.33
