Answer:
by friday she will run about 25 miles total, so using process of elimination, it will be about 35. so she will run about 15 miles in total. if this is incorrect, then its 18 if she pushed her limits
Explanation:
considering you uploaded this on thursday, and she has ran 20 miles this week, use 20 divided by 4, and you get 5. now, with that logic, i assume she runs about 5 miles a day. and 5 times 7 equals 35, which is also less than 38.
