Problema Solution
After knee surgery, your trainer tells 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 that you
increase that time by 6 minutes per day. How many weeks will it be before you are up to jogging 60
minutes per day?
Answer provided by our tutors
first week: 12
second week: 12 + 6
third week: 12 + 6 + 6 = 12 + 2*6
forth week: 12 +2*6 + 6 = 12 + 3*6
n th week: 12 + (n - 1)*6
12 + (n - 1)*6 < 60
by solving we find
n < 9 weeks
