Yosef Weiss · Answer 1

A) 72 kilometers per hour

Step-by-step explanation:

It goes 72 kilometers per hour because to there are 60 seconds in a minute and so you have to multiply 20 * 60 so, 1200 meters per minute and there are 60 minutes in a hour so you multiply 1200 * 60 so, that is 72,000 meters per hour. and since there are 1,000 meters in one kilometer you divide 72,000 so 72 kilometers per hour.
