A long-distance athlete can run 1/2 kilometer in 3 minutes. How many kilometers can he run in an hour?

1 answer:

5 0

He can run 10 km in an hour. 60 minutes divided by 3 is 20km. 20 would be the answer, but that's only if he runs 1km in 3 minutes. Since he runs .5km in 3 minutes, you need to divide the 20 by 2. Therefore, you have 10km in 1 hour
