After knee surgery, your trainer advises you to return to your jogging program slowly. He suggests jogging for 12 minutes each day for the first week. Each week thereafter, he suggests increasing that time by 6 minutes per day.

How many weeks will it be before you are up to jogging 60 minutes per day?

Answer :

Answer: it will take 9 weeks before you are up to jogging 60

minutes per day.

Step-by-step explanation:

jogging for 12 minutes each day for the first week. Each week thereafter, he suggests that you

increase that time by 6 minutes per day. This means that the number of minutes is increasing by 6 for each week. This is an arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 12 minutes

d = 6 minutes

n = 25

Tn = 60 minutes

We want to determine number of weeks it will take to reach 60 minutes per day. Therefore,

60 = 12 + (n - 1)6

60 = 12 + 6n - 6

6n = 60 - 12 + 6

6n = 54

n = 54/6 = 9

Final answer:

It will take 9 weeks to reach jogging 60 minutes per day.

Explanation:

To determine the number of weeks it will take for you to reach jogging 60 minutes per day, we can set up an equation. Let's say x represents the number of weeks. The total jogging time can be represented using the formula 12 + 6(x-1). We need to solve for x when the total jogging time is 60 minutes.

12 + 6(x-1) = 60

6(x-1) = 48

x-1 = 8

x = 9

Therefore, it will take 9 weeks for you to reach jogging 60 minutes per day.
