Answer:

15 km/h

Explanation:

Leo takes 15 minutes to cycle to school at an average speed of 12 km/h. What speed will he have if he only takes 12 minutes?

15 minutes * (1 hour)/(60 minutes) = 0.25 hour

speed = distance/time

distance = speed * time

distance = 12 km/h * 0.25 hour = 3 km

He cycles a distance of 3 km.

12 minutes * (1 hour)/(60 minutes) = 0.2 hour

speed = distance/time

speed = 3 km/(0.2 hour)

speed = 15 km/h
