Answer:
3 hours 30 minutes
Step-by-step explanation:
Since,
1 hour = 60 minutes,
1 minute = 60 seconds,
⇒ 1 hour = 60 × 60 = 3600 seconds,
[tex]\implies 1\text{ second}=\frac{1}{3600}\text{ hour}[/tex]
Thus, the number of hours in 12,600 seconds = 12600 × number of hours in 1 second
[tex]=12600\times \frac{1}{3600}[/tex]
[tex]=\frac{126}{36}[/tex]
[tex]=3\frac{1}{2}[/tex]
= 3 hours 30 minutes ( ∵ 1/2 hours = 30 minutes )
