My question is: Ms. Warren ran at 6 mph for 20 minutes. After the run, she walked at 2 mph for 30 minutes. How many miles did she run and walk in total? Your thoughts:

20 minutes is 20 / 60 = 1 / 3 of an hour. Ms. Warren ran 6 / 3 = 2 miles. 30 minutes is 30 / 60 = 1 / 2 of an hour. Ms. Warren walked 2 / 2 = 1 mile. Ms Warren ran and walked 2 + 1 = 3 miles in total. The final answer: 3.
