The first thing you need to do it convert 81 kilometers per hour to per minute. There are 60 minutes in one hour, so you would divide 81 and 60.
81/60=1.35 kilometers per minute

Now that you know how fast the car is traveling per minute, you can easily find how far the car will travel in 15 minutes.
1.35*15= 20.25
The car will travel 20.25 kilometers.

Hope this helps :)
