Question

Mikaela is competing in a race in which she both runs and rides a bicycle. She runs 4.5 kilometers in 0.5 hour and rides her bicycle 18.75 kilometers in 0.75 hour. If she runs for 1 hour and bikes for 1 hour at the same rates as she does in the race, how far will she travel? Explain you reasoning.

Answer 1

She will travel 34 kilometers because if she runs 9 kilometers in 1 hour and bikes 25 kilometers in 1 hour, then 9+25=34.
