Acar is traveling at a rate of 81 kilometers per hour. what is the cars rate in kilometers per minutes?

If the car can travel 81 km in one hour, (60 minutes) that means that it can travel 81/60 in a minute. The result is 1.35, and this times 15 will give you the amount the car can travel in 15 minutes. The answer is 20.25km. Then you would divide 20.25 and 15 to get your answer.

The correct answer is $90
