Mikaela is competing in a race in which she both runs and rides a bicycle. She runs 5 kilometers in 0.5 hour and rides her bicycle 20 kilometers in 0.8 hour
To find Mikaela's average speed for both running and biking, we need to calculate the total distance she travels and the total time it takes her.
First, let's calculate the total distance:
She runs 5 kilometers + rides her bicycle 20 kilometers = <<5+20=25>>25 kilometers
Next, let's calculate the total time:
She runs for 0.5 hours + rides her bicycle for 0.8 hours = <<0.5+0.8=1.3>>1.3 hours
Now, we can calculate her average speed:
Average Speed = Total Distance / Total Time
Average Speed = 25 kilometers / 1.3 hours
Simplifying the calculation:
Average Speed = 19.23 kilometers per hour
Therefore, Mikaela's average speed for both running and biking is 19.23 kilometers per hour.
