2. QUIT WHILE YOU CAN Smoking has long been connected with serious diseases, such as lung cancer,
den301095 [7]

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.
