The correct answer is: $36000\text{ s}$
Explanation
We convert hours → minutes → seconds. One hour has 60 minutes and one minute has 60 seconds, so multiply accordingly.
Steps:
- $1\text{ hr}=60\text{ min}$
- $1\text{ min}=60\text{ s}$, so $1\text{ hr}=60\times60=3600\text{ s}$
- $10\text{ hr}=10\times3600=36000\text{ s}$
Therefore, 10 hours equals $36000\text{ s}$.
