Final answer:
To achieve her goal of running a mile in 6 minutes, Jami needs to set the treadmill speed to 10 miles per hour.
Step-by-step explanation:
Jami's goal to run a mile in 6 minutes on a treadmill converts to a speed she needs to set in miles per hour (mph). To find this, we can use the ratio of the distance over time and convert the time from minutes to hours. Since there are 60 minutes in 1 hour, we set up the ratio as 1 mile/6 minutes which is equivalent to 1 mile/(1/10 hours) because 6 minutes is 1/10th of an hour.
Therefore, by simplifying, we get the speed as 1 mile/(1/10 hour) = 10 mph. So, Jami needs to set the treadmill to 10 miles per hour to achieve her goal of running a mile in 6 minutes.
