Final answer:
Upon converting 4 hours into seconds, which is 14,400 seconds, it is determined that 4 hours is equal to 14,400 seconds.
Step-by-step explanation:
To determine if 4 hours is greater or less than 14,400 seconds, we must first convert the hours into seconds. We know that 1 hour is equal to 60 minutes, and each minute is equal to 60 seconds, hence 1 hour is 3600 seconds. Therefore, 4 hours is 14,400 seconds (4 hours × 3600 seconds/hour).
Comparing the two numbers now, 14,400 seconds and 14,400 seconds, we can see that they are exactly the same amount of time. Hence, 4 hours is equal to 14,400 seconds.
