A Is The Correct answer

Kylan Hall · Answer 2

1 week is 7 days.

3 weeks = 21 days. Answer D. is correct.

A hour is 3600 seconds

24 hours (a day) is 86400 seconds

21 days is 1814400 seconds. * This is not an option *

Since 24 hours are in a day 24 hours x 21 days is 504 hours

Answer A. is correct

504 hours x 60 minutes per hour is 30240

Answer B. is correct. These are all the correct answers, A, B, and D.
