Elias started her season running a 7 minute mile and is reducing her time by five seconds a week what equation describes Elias time in weeks
x = week
x week = 7 minutes per mile - 5 seconds * x
Now put the value of x as the number of the week, then you will get the time in weeks.
For example, if we put 1, then
1 week = 7 minutes per mile - 5 second * 1
1 week = 7 minutes per mile - 5 second
1 week = 6 minutes 55 seconds per mile.
