There are 60 seconds in a minute and 60 minutes in an hour. To calculate the number of seconds in 2 hours, you can multiply the number of minutes in 2 hours by 60 (since there are 60 seconds in a minute).
Number of seconds in 2 hours = 2 hours * 60 minutes/hour * 60 seconds/minute
Performing the calculation:
2 hours * 60 minutes/hour * 60 seconds/minute = 2 * 60 * 60 = 7,200 seconds
Therefore, there are 7,200 seconds in 2 hours.
