Answer:
9.09 times that by 6.666 and you get 60
Explanation:
You need to make it a full mile meaning you have to multiply 1/10 mile by 10. this gives yoy one mile. You need to do this to 2/3 minute as well. it gives you 20/3 minute or 6 2/3 minute. Theoretically, if she could mantain this pace for a whole hour she could run about 9.09 miles an hour.
The explination behind my answer is just multiplying the 6.666... by 9.09 and it should be as close as it can be to 60 (minutes)
