Oscar is training to compete in a cross country meet at his school. In a week he runs a total of 7 miles in 84 minutes. What is the unit rate of minutes per miles?

Answer 1

To find the unit rate of minutes per mile, divide the total number of minutes by the total number of miles.
Unit rate of minutes per mile = 84 minutes / 7 miles = <<84/7=12>>12 minutes/mile. Answer: \boxed{12}.
