Question

Suppose the U.S. national debt is about $15 trillion.

Answer 1

Answer:

It is going to take 118.9 years to pay off the debt, assuming no interest was charged.

Explanation:

The first step to solve this question is to know how many dollars are paid per year.

How many seconds are in an year?

An year has 365 days.

Each day has 24 hours.

Each hour has 60 minutes.

Each minute has 60 seconds.

So each year has 365*24*60*60 = 31,536,000 seconds.

How much is paid a year?

Payments made at the rate of $4,000 per second.

So in an year, 4,000*31,536,000 = 126,144,000,000 dollars are paid in an year.

How many years would it take to pay off the debt, assuming no interest was charged?

The debt is $15 trillion = 15,000,000,000,000.

This can be solved by a simple rule of three

1 year - $126,144,000,000

x years - $15,000,000,000,000

$126144000000x = 15000000000000$

$x = \frac{15000000000000}{126144000000}$

$x = 118.9$

It is going to take 118.9 years to pay off the debt, assuming no interest was charged.
