If a person smokes 20 cigarettes in a day for 58 years of their life, how many cigarettes do they smoke?
If each cigarette reduces a person's life by 5 minutes, by how many days is a person's life reduced if they smoke 20 cigarettes a day for 58years of their life?
Please can you help me to solve? Am having trouble working out the second part. Thanks Sam
Part 1: 58 years will probably include 15 leap years, so the number of days is
(58x365) + 18 = 21,188
Multiply that by 20 for the number of cigarettes smoked: 423,760
Part 2: Multiply 423,760 by 5 for the number of minutes that the length of life is reduced, and convert numbewr of minutes that to years.
I get about 4 years.
Thank you

1.423760 2.4 years
Of course, Sam! I'll help you with both parts of your question.
First, let's find out how many cigarettes the person smokes in total. To do this, we can multiply the number of cigarettes smoked per day by the number of years:
Cigarettes smoked per day = 20 cigarettes
Number of years = 58 years
Total cigarettes smoked = Cigarettes smoked per day × Number of years
Total cigarettes smoked = 20 cigarettes/day × 58 years
Total cigarettes smoked = 1,160 cigarettes
So, the person smokes a total of 1,160 cigarettes in 58 years.
Now, let's move on to the second part of your question.
If each cigarette reduces a person's life by 5 minutes, we need to calculate how many minutes their life is reduced by in total. We can then convert that into days.
Total minutes lost = Total cigarettes smoked × Minutes lost per cigarette
Total minutes lost = 1,160 cigarettes × 5 minutes/cigarette
Total minutes lost = 5,800 minutes
To convert minutes into days, we need to know how many minutes are in a day. There are 24 hours in a day, and each hour has 60 minutes.
Total minutes in a day = 24 hours × 60 minutes/hour
Total minutes in a day = 1,440 minutes
Now, let's calculate the number of days a person's life is reduced by:
Days of life lost = Total minutes lost / Total minutes in a day
Days of life lost = 5,800 minutes / 1,440 minutes/day
Days of life lost = 4.03 days
Therefore, if a person smokes 20 cigarettes a day for 58 years, their life is reduced by approximately 4.03 days.
I hope this helps! Let me know if you have any further questions.
