Question

2. QUIT WHILE YOU CAN Smoking has long been connected with serious diseases, such as lung cancer,

Answer 1

Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.

---------------------------

• 2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as $35 \times 365 = 12775$.
• Thus, a total of 511000 cigarettes, as $40 \times 12775 = 511000$.
• Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as $15 \times 511000 = 7665000$

• One year has 525600 minutes, thus the person loses 14 years of life, as $\frac{7665000}{525600} = 14.5833333$

• Looking at the decimal part, the person loses 212 days of life, as $0.5833333 \times 365 = 212.916666655$
• Again looking at the decimal part, 22 hours, as $0.916666655 \times 24 = 22$

• Thus, the person loses 14 years, 212 days and 22 hours of life.
