1 light-hour = 1.07925285 × 109 kilometers.
miles... in kph??? Anyway, the speed of light is 300,000 kilometers/second; you can convert that to whatever unit you want. For example, to convert to kilometers/hour, multiply by 3600.
That depends on the speed. Choose a suitable speed, then divide the distance by the speed. If the distance is in kilometers, and the speed is in kilometers/hour, then the time will be in hours.That depends on the speed. Choose a suitable speed, then divide the distance by the speed.

In a vacuum, the speed of light is always 670,616,629 miles per hour (300,000 kilometers per second). The speed of light changes as it enters a different medium, such as Earth's atmosphere, but the change in speed is essentially negligible.
You can't compare a distance (in kilometers) with a speed (in kilometers per hour).
About 300,000 kilometers per second.
That depends on the speed. Assume a speed (in kilometers per hour), then divide the distance by the speed. Answer is in hours.
The speed in km/hour must be given. The answer is obtained by dividing 250 km by speed in km/hour
One lightyear is equivalent to 9.461 trillion kilometers. To find the distance in kilometers per hour, you would need to divide this by the number of hours in a year (8,760 hours). This would give you approximately 1,080,815,900 kilometers in one lightyear per hour.
If 1 hour ===> 40 km, then 2 hours ===> 80 km.
the speed of garden snail in kilometres per hour is 0.048 km/h
That depends at what speed you are travelling.
