Question Rachel ran an average of 30 miles this week. She ran 8 miles on Monday. How many miles did she run on average the other four days of the week?
Answer This problem is worded funny. If the question is:
Rachel ran an average of 30 miles PER DAY this week.
Then here is the answer.
(8 + TWThF)/5 = 30
TWThF = 150 - 8
TWThF = 142
Average of TWThF = TWThF/4 = 35.5 miles
If the question is:
Rachel ran 30 miles this week.
8 + TWThF = 30
TWThF = 22
Average of TWThF = 22/4 = 5.5
My suspicion is that the first answer is the one they are looking for. Let me know if I can help further.
