My question is: Jim ran 16 miles in 2 hours while Frank ran 20 miles in 2 hours. How many more miles did Frank run than Jim in an hour? Your thoughts:
Jim ran 16 / 2 = 8 miles for an hour. Frank ran 20 / 2 = 10 miles for an hour. Frank ran 10 - 8 = 2 more miles than Jim in an hour. The final answer: 2.
