While Paul watches movies, he runs on his treadmill. He can run a mile in 12 minutes. He watches two movies, which are an average length of 1.5 hours. How many miles does he run? Let's be accurate as possible.
He runs for 3 hours because 2 x 1.5 = 3. He runs for 180 minutes because 3 x 60 = 180. He runs 15 miles because 180 / 12 = 15.
The answer: 15.
