A Singaporean has assets of $5 billion.If he spends $10 every second,how long will it take for him to spend all his money
500 million seconds
138,880 hours
5786.667 days
190.246 months
8332800 minutes
you have an arithmetic sequence with
a = 5,000,000,000
d = -10
n = ?? , where n is in seconds
term(n) = a+(n-1)d
you want term(n) = 0
5,000,000,000 + (n-1)(-10) = 0
-10n + 10 = -5000000000
-10n = -5,000,000,010
n = 500,000,001 seconds
= 8,333,333.35 minutes
= 138,888.89 hours
= 5787.0 days
=15.85 years
To calculate how long it will take for the Singaporean to spend all his money, we can divide his total assets by the rate at which he is spending.
1. Calculate the total number of seconds it will take to spend $5 billion:
Total seconds = Total money / Money spent per second
= $5,000,000,000 / $10
= 500,000,000 seconds
2. Convert the total number of seconds into a more understandable format:
Days = Total seconds / (24 * 60 * 60)
= 500,000,000 / (24 * 60 * 60)
≈ 5787.04 days
Therefore, it would take approximately 5787 days (or about 15.85 years) for the Singaporean to spend all his money if he spends $10 every second.
