First, calculate the distance Wonderworks ran during the first 45 minutes:
Distance = speed x time
Distance = 3 km/h x 0.75 h
Distance = 2.25 km
Now, calculate the distance Wonderworks ran during the second half hour:
Distance = speed x time
Let the average running speed during the second half hour be x km/h.
Distance = x km/h x 0.5 h
Distance = 0.5x km
Given that the total distance traveled is 6 km:
Total distance = 2.25 km + 0.5x km
6 km = 2.25 km + 0.5x km
3.75 km = 0.5x km
x = 7.5 km/h
Therefore, Wonderworks' average running speed during the second half hour was 7.5 km/h.
Wonderworks at an average speed of 3 km per hour for 45 minutes before running for half an hour at a certain average speed if she travels a total distance of 6 km calculator average running speed
