Final answer:
To find out how many years older you will be 1.50 billion seconds from now, divide 1.50 billion by 86,400 to find the number of days. Then, divide the number of days by 365 to find the number of years.
Step-by-step explanation:
There are approximately 365 days in 1 year. To determine the number of seconds, we must estimate the number of seconds in 1 day. We can change units as follows (notice how the units of time cancel out):
1 day × 24 hr/day × 60 min/hr × 60 s/min = 86,400 s/day
Therefore, there are 86,400 seconds in a day. To find out how many years older you will be 1.50 billion seconds from now, divide 1.50 billion by 86,400 to find the number of days. Then, divide the number of days by 365 to find the number of years.
