Below The Answer
The speed of light in a vacuum is approximately 299,792,458 meters per second. To convert this to kilometers per hour (kph), we can use the following steps:
Convert meters to kilometers by dividing by 1,000:
299,792,458 meters/second = 299,792.458 kilometers/second
Convert seconds to hours by multiplying by 3,600 (the number of seconds in an hour):
299,792.458 kilometers/second * 3,600 seconds/hour = 1,079,252,849.28 kilometers/hour
Therefore, the speed of light in kilometers per hour is approximately 1,079,252,849.28 kph
