Smoking has long been connected with serious diseases, such as lung cancer, emphysema, and heart disease. Let's estimate that for every cigarette a person smokes, he or she loses anywhere from 10 to 15 minutes of his or her life. Assuming the worst (15 minutes of life lost for each cigarette), how much shorter would the life span be of someone who smoked 2 packs a day for 35 years? (Each pack contains 20 cigarettes.) Answer in years, days, hours, and minutes.

15 minutes/cig * 2 packs/day * 20 cig/pack * 30 years

this will give you the answer in years and fractional year

to get the fractional year into the units required, you can multiply just the fractional part of the answer above * 365 (ignoring leap-year effects)

this will give you the answer for days and a fractional day

multiply just the fractional part of this answer by 24

this will give you the answer for hours and a fractional hour

multiply just the fractional part of this answer by 60

this will give you the answer for minutes (round off the number to the nearest minute)

This is easy. Ignoring leap year effects,
35 years * 365 days/year * 2 packs / day * 20 cigs / pack * 15 minutes /cig = 7665000 minutes = 127750 hours = 5322 days 22 hours = 14 years 212 days 22 hours
