Question

Annie has set a goal of running at the track three times each week for a total of at least 16 miles per week. On Monday she ran 7.1 miles, and on Wednesday she ran 5.9 miles. If Annie plans to go running again on Friday, what is the minimum number of miles needed to reach her weekly goal?

Answer 1

She needs to run a minimum of 3 miles
The total of what she ran so far is 13 miles
So then you would subtract 13 from the total of 16 miles to get a minimum of 3 miles
