To train for a race, Will begins by jogging 11 minutes one day per week. He increases his jogging time by 5 minutes each week. Write the general term of this arithmetic sequence, and find how many whole weeks it takes for him to reach a jogging time of one hour

Eq: T = 5W + 11.
Example: Let W = 4 weeks.
T = 5*4 + 11 = 31min.
T = 1hr = 60min.
T = 5W + 11 = 60min,
5W + 11 = 60,
5W = 60 - 11 = 49,
W = 49 / 5 = 9.8wks or 9 Whole weeks.
