How many seconds are in one hour?

• A. 1800 seconds
• B. 7200 seconds
• C. 3600 seconds
• D. 360 seconds

Answer: (C)

Converting hours to seconds relies on how time units relate: 1 hour contains 60 minutes, and each minute has 60 seconds. Multiply 60 by 60 to get 3600 seconds in one hour. So the correct value is 3600 seconds. The other numbers correspond to different durations: 1800 seconds is half an hour, 7200 seconds is two hours, and 360 seconds is six minutes.
