Best Answer

Light is so fast that it is usually expressed as about 300,000 kilometers per second. If you multiply that by 3600 seconds / hour, you get the speed in kilometers per hour.

1500 kilometers how many hours to drive?

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.

How many miles per hour does it take for light to travel from the sun to the earth?

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.

How many kilometers in one lightyear per hour?

A light year is the distance that light will travel in a vacuum in a year. Nothing can travel that distance in an hour so a lightyear per hour is a meaningless concept of speed. Though impossible to attain, it is a measure of speed while a kilometre is a measure of distance. There is no direct relationship between the two.
