Question

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 hours

Answer 1

Mikaela's average speed for the entire race is (5 + 20) / (0.5 + 0.8) = 15 kilometers per hour.

Mikaela can bike 25 kilometers in 1 hour. This is because she biked 20 kilometers in 0.8 hours, which can be converted to 25 kilometers in 1 hour (20 kilometers / 0.8 hours = 25 kilometers / 1 hour).
