Average rate= Total distance
---------------
Total time
Suppose a person travels 10 miles in 1/3 of an hour, then returns by traveling that same 10 miles in 1/4 of an hour. What is that person's average rate?
1/3 + 1/4 = 7/12 of 60mins. = 35mins total time, so 20/35 = .57
This isn't the right answer.
