Given 60 seconds to a minute and 24 hours to a day, how many seconds are in one year?

Rationale

A) 31,536,000 is the correct answer.

The exact number of seconds in a year depends on how one defines a year. In a non-leap common year of 365 days, the total number of seconds equals 365 days * 24 hours/day * 60 minutes/hour * 60 seconds/minute, which equals 31,536,000 seconds. In a leap year of 366 days, an additional 86400 seconds are added, totaling 31,622,400 seconds.

B (########) YOUR ANSWER

This value is an incomplete of the actual value

C (8,760) YOUR ANSWER

This number represents the total hours in a year (365 days * 24 hours/day). However, the question asks for the total number of seconds in a year, not hours, making this choice incorrect.

D (525,000) YOUR ANSWER

This number approximates the total minutes in a year (365 days * 24 hours/day * 60 minutes/hour). But the question requests the total number of seconds in a year, not minutes, rendering this choice incorrect.

Conclusion

The total number of seconds in a non-leap year equals 31,536,000 and in a leap year equals 31,622,400. As such, the answer to the question of how many seconds are in a year, given 60 seconds to a minute and 24 hours to a day, is correctly represented by option A . All other options fail to provide the correct number of seconds, instead representing hours (C) or minutes (D) in a year.

Given 60 seconds to a minute and 24 hours to a day, how many seconds are in one year?

A) 31,536,000 is the correct answer.
