###Human: Luis is driving 80 miles in 2 hours. How far will he go in 15 minutes?, ### Assistant: Luis drives 80/2 = 40 miles in 1 hour.
Since there are 60 minutes in 1 hour, then he drives 40/60 = 2/3 of a mile in 1 minute.
So in 15 minutes, he will go 2/3 x 15 = 10 miles far. 
 So the answer is :  10
