To find Michaela's average speed for the entire race, we need to calculate her total distance and total time.
Her total distance is 5 km + 20 km = 25 km.
Her total time is 0.5 hours + 0.8 hours = 1.3 hours.
Now, we can calculate her average speed by dividing her total distance by her total time:
Average Speed = Total Distance / Total Time
= 25 km / 1.3 hours
≈ 19.23 km/h
Therefore, Michaela's average speed for the entire race is approximately 19.23 km/h.
Michaela is competing in a race in which she both runs and ride a bicycle. She runs 5 kilometers in 0.5 hour and ride her bicycle 20 km in 0.8 hour.
