How do I concert 6900 seconds into weeks

I think you are supposed to divide the seconds by 7?

0.01 weeks (rounded)

Step-by-step explanation: You use conversion factors:

6900 s * 1 hour/ 3600 s * 1 day/24 hour * 1 week/ 7 days

Seconds, hours, and days cancel, and you get 0.01140873 weeks, which is approximately 0.01 weeks.
