Carly says she walks 300 millimeters to school each day. Is this reasonable? Explain.

No, this is not reasonable because 1000 millimeters are in ONE meter. One meter is about three feet. Unless Carly lives in school, then no, this is not reasonable.

No this is not reasonable at all! 300 millimeters is basically nothing. 300 millimeters is equal to 0.00018641 miles which is not much at all. instead of using millimeters, which are too small to measure distance, she could use feet since she is walking to school each day.
