Question

An Olympic athlete is recovering from knee surgery and she is under a doctor's care. The doctor has the athlete jog 12 minutes a day for five weeks. After that, the athlete will increase the jogging time by five minutes a day, a week at a time. In what number week will the athlete be jogging more than a hour per day??
A) Week 17

B) Week 13

C) Week 15

D) Week 12

Answer 1

Here, Your Inequality would be:
12 + 5x ≥ 60
Subtract 12 from both sides, 
5x ≥ 48
Divide by 5, 
x ≥ 9.6

Number of weeks can't be in fraction, so it would be 10 plus that initial 5 weeks so in total it is 15

In short, Your Answer would be Option C

Hope this helps!
