Final answer:
The speed of light in kilometers per hour is obtained by multiplying the speed of light in kilometers per second (300,000 km/s) by the number of seconds in an hour (3,600), which equals to 1,080,000,000 km/hr.
Step-by-step explanation:
To find out the speed of light in kilometers per hour, we would use the given value for the speed of light in meters per second and convert it to kilometers per hour. We know that the speed of light is approximately 300,000 kilometers per second, or 300,000,000 meters per second. To convert this to kilometers per hour, we multiply by 3,600, which is the number of seconds in one hour:
- (300,000 kilometers/second) × (3,600 seconds/hour) = 1,080,000,000 kilometers/hour.
So, the speed of light in kilometers per hour is 1080000000 km/hr, which corresponds to answer option A.
