Question

If you earn one penny every 10 seconds of your life ,how many dollars would you have after 65 years?

Answer 1

How many seconds are in 65 years:
65 years × 362.25 days × 24 hours × 60 min × 60 seconds = 2,051,244,000 seconds in a year (÷ 10 seconds = 205,124,000 pennies)

The answer is 205,124,000 pennies

Answer 2

$205122240

Explanation:

We know that there are
`100` pennies in $1.

Number of seconds per minute =
`60` seconds

Number of minutes per hour =
`60` minutes

Number of hours per day = 24 hours

Number of days per year = 365 days

∴ Number of seconds per day =
`60*60*24 = 86400` seconds

and number of seconds per year =
`60*60*24*365 = 31536000` seconds

Number of seconds in 65 years =
`31536000*65 = 2049840000` seconds

now, there are 366 days in a leap year, considering every fourth year to be the leap year, we will have 16 leap years

∴ there will be 16 extra days

number of seconds in 16 days =
`86400*16 = 1382400` seconds

∴ total number of seconds in 65 years =
`2049840000 + 1382400 = 2051222400` seconds

total earning =
`2051222400*10 = 20512224000` Pennies

total earnings in dollars =
`(20512224000)/(100) = 205122240`
