math

A runner times herself to see how long it takes her to run different distances. The table shows the runner's times (in minutes) for running several distances (in miles).
Miles: 1|2|3|4|6|8|10|12
Time: 7|16|30|35|57|75|106|132
About how long would you expect it to take this runner to run 17 miles? Find a line of best fit for this data and use it to make your prediction.
205 mins
172 mins ~~~
161 mins

  1. Hmmm. I got 183, with the best-fit line being

    y = 11.155251x - 6.892694

    what did you get, and how?
