Lin has a watch that counts the number of steps she takes during the day. The watch displays her steps in centimeters, meters, or kilometers.

Here is a list of activities Lin did on Monday. Next to each activity, write whether it would make sense to display the distance in centimeters, meters, or kilometers.
- walked to her friend’s desk
- walked to the front of the classroom
- walked from her classroom to the bus
- ran twice around the playground
- The table shows the amount of steps Lin’s watch displayed for each activity. If each of Lin’s steps is 50 centimeters, how many centimeters and how many meters did she walk for each activity?
