Question 984684: After a knee surgery your trainer tells you to return to your jogging program slowly.he suggest jogging for 12minute each day for the first week.each week thereafter he suggested that you increase that time by 6minute per day. How much weeks will it be before you are upto jogging 60minute per day
Answer by vleith(2983) About Me  (Show Source):
You can put this solution on YOUR website!
The equation for how long your are running each day is given by
12+%2B+%28w-1%296
That says in the first week, you will run 12+(1-1)6 = 12
The second week you will run 12+ (2-1)*6 = 18 minutes etc
You are asked, how many weeks before you are running for 60 minutes?
{{[RunningTime = 12 + (weeknumber -1)*6}}}
60+=+12+%2B+%28weekNumber+-1%29%2A6
48+=++%28weekNumber+-1%29%2A6
48%2F6+=+%28weekNumber+-1%29
8+=+weekNumber+-1
9+=+weekNumber
So by the 9th week, you are running for 60 minutes.
Go easy on that knee!
