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 

Apr 2nd, 2015

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.
